I favor discrete effects loops on rackmounted shelves, since I’m not a stomping-on-stage kind of guy.
As evidenced by a few recent posts here on Noise Jockey, I think the most exciting way to use guitar-oriented effects pedals is thinking of them as modular synthesizer units. (Indeed, it’s no accident that many boutique pedal makers are now issuing Eurorack versions of their stompboxes.) My workflow usually involves recording signals dry, then running them through the effects as sends. This gives me maximum control when composing, designing, and mixing. I keep my pedals in two distinct loops: One for sculpting and distorting tone, and one for filtering and modulation.
However, just sending signals out to pedals as effect sends from an audio interface doesn’t always work very well. Most effect pedals expect guitars at their front door, not synths, virtual instruments, samples, or field recordings. Most guitars with passive pickups, of course, are high-impedance instrument-level signals, not low-impedance line-level signals that one would expect from hardware synths, virtual instruments, or pre-recorded tracks that are coming back out via an audio interface. This can mean that the effect return might be extremely low, distorted, or noisy/hissy, depending on the signal and what specific pedals are in the effects chain.
So, there are basically two ways to address this problem.
- Use pedals that natively support line-level signals. This usually leads one to higher-end pedals like the Moogerfoogers, and they can be expensive. Rackmount multi-effect units often handle line inputs just fine, but many of those units are also expensive and, in my experience, lack the character and flexibility of a more modular approach of individual pedals. My bigger issue with this approach is that it seems silly to limit one’s creativity based on the vagaries of electrical engineering.
- Use a device in the effects chain to properly match impedances of the sent signal to the effects in the chain. This approach gives the designer, artist, musician, or engineer the best balance of creative freedom while correct managing signal level to optimize frequency response, gain, and noise levels.
DI (direct injection) boxes won’t solve this problem, since they usually output at microphone level – still a high impedance signal. No, dear friends, what you really want is a re-amping device, a box that takes any pre-recorded signal and sends it to a guitar amp or effects chain as a high impedance signal. These are as expensive as decent effect pedals themselves, but worth their weight in gold to treat your audio right and send any signal to any effect. A most egalitarian piece of electronic equipment. Many reamp devices exist, even as 500 series modules!
But remember my two-loop effects chain? Ostensibly I’d need a re-amp on each chain; that sounded expensive. Or so I thought, until I discovered the Pigtronix Keymaster.
There is no impedance, only Zuul.
Besides the obvious bonus of being named after a Ghostbusters reference, the Keymaster has two dedicated re-amping loops, each with a send and return and individual loop output gain knobs. PERFECT. Heck, it even sports XLR I/O for the fancy lads and lasses. As an added weird bonus, it actually has a crossfader between each loop, should one want to switch between the two in real time. While I have used this myself musically, most of the time this large green and white box stays in the back of my effects back near my power simply, silently channeling and impedance-matching my dry signals into mangled layers of noisy glory.
Many other re-amping boxes exist, and single-channel units are cheaper, but for maximum creative weirdness and flexibility, the Keymaster has become the core of my externalized sound design and musical effects chain, even when it’s simply a silent partner in making noisy things happen. Heck, it even lets me run them in serial or parallel, and freed up some I/O plugs on my patchbay and audio interface.
So, if you’re interested in experimenting with effects pedals and stomp boxes as external effects devices, grab a re-amping box and hit eBay or your local guitar shop in search of fun stompboxy goodness. We’re in a golden era of boutique audio hardware creation, so there’s no better time to experiment with literally out-of-the-box noisemaking.
Today’s sound is an extremely simple drum loop, but using a bunch of effect pedals, all managed through the Keymaster. First you’ll hear a rhythmic start with just a Dwarfcraft Robot Devil pedal, with only its starved circuit creating the rhythm, being run through a Red Panda Particle pedal set on delay. Then you’ll hear a hi-hat run through a Snazzy FX Wow and Flutter pedal. A dry kick drum then starts, and the snare eventually gets the Red Panda Particle treatment as a super-wet granular delay.

Sometimes sound design requires thinking inside of multiple boxes.
I’ve developed a small collection of handmade and boutique electronic effects and instruments over the years, like the Grendel Drone Commander, Lite2 Sound PX, and many more (perhaps the subject of another post). Longtime readers may recall that I just love supporting independent makers and small cottage industries: That’s where all the weird, truly innovative stuff happens, and I (like many of you, dear readers) am more interested in cool sound design possibilities than straight-up distorted guitarrrrrrrr sounds.
Beyond this, I’ve also been expanding my collection of effects pedals. My latest three are definitely the weirdest: The Great Destroyer and Robot Devil from Dwarfcraft Devices, and the Wow & Flutter from Snazzy FX.

Rare Waves’ Lite2Sound PX, by Eric Archer: A photonic microphone!
I’ve previously written about the heavily-built, wickedly cool Grendel Drone Commander synth from Eric Archer. I check his site, Rare Waves, from time to time for new handmade electronic toys, and I was really intrigued by his newer Lite2Sound PX unit. This small device, in Eric’s words, “extracts audio from ambient light.” It’s a photodiode amplifier. Or a photosensitive microphone. Point it at light, it makes sound. It runs off a 9-volt battery, has a volume control, and a headphone jack. Simple, exciting, and a whole new world of sonic insanity. You can buy them as kits or, as I did, fully assembled.
Sounds pretty straightforward. If you just point it at bright, broad light sources, it’s kind of disappointing. It’s when you start listening to artificial lights in otherwise dim environments that some serious magic starts to happen. My experiments were conducted in and around high tech computer equipment, running an 1/8″ mini jack from the headphone output into my Sony PCM -D50 recorder.
Lights inside of PCs, modulated by fans…and further modulated by speaker grills as I passed the Lite2Sound from side to side. Ethernet network activity lights. Server disk access indicator lights. A close up of the power button of an XBox 360 while booting up. Pulsing lights of devices in standby mode. Halogen lamps behind spinning desk fans.
Lightly armored for future fieldwork!
The resulting sounds were astounding in their range: Static, glitches, distorted synth pads, pure sinewave tones, sawtooth-like tones, and much more. You can’t control it, really. It’s a tool of discovery, and its very nature encourages constant experimentation. It was so small and so perfectly complemented a handheld field recorder, I just wanted to take it everywhere and point it at everything! It imparted the same joy as when you start recording with contact microphones, or hydrophones: A new way to listen to the world around you. The more I used the Lite2Sound, I put it in a small plastic container (hacked with an XActo knife for access to controls and the headphone jack) in order to keep the components better protected.
Lite2Sound is a pretty narrowly-focused device and how useful it is to you depends on your taste for the unpredictable. Me, I adore this thing. Hell, I bought two (for future stereo photo-phonic insanity). It encourages constant experimentation, weighs nothing, and I can see using its output in both sound design and musical contexts. Eric Archer nails it again with an odd concept and a rock-solid, focused execution that results in a toy that just begs to be played with.

This thing was given to me as a Christmas gift. I immediately wanted to not froth milk with it, but to record it. With a hydrophone.
It was initially disappointing…until I put it into a metal pan and realized that its interaction with the pan, not the water, was far more interesting. The hydrophone was still in the water, but the frother was used in the water, inside the pan, and outside the pan as well, at varying speeds.

“Construction 129,” a never-completed gun emplacement overlooking the entrance of the Golden Gate, Fort Cronkhite, Marin Headlands, California.
When a winter storm was forecast for the San Francisco Bay Area, I decided to head to the Marin Headlands and try my luck recording bad weather in the abandoned gun emplacements and military fortifications of Fort Cronkhite. I had previously found some great metal sounds at Fort Baker, also in the Headlands, and I was also inspired by Tim Prebble’s high-wind-sub-bass-generator post.
Unfortunately for me, the storm track was slower than predicted, and I wasn’t able to record in peak wind, although some moderate rain started to fall. Such things happen, even with the best of intentions. So, what do you do when your primary plan doesn’t pan out? You reset your expectations and record what you can. I mean, c’mon, I’m in these amazingly evocative ruins! Surely there’s something that’s audibly interesting!
So, I decided to record rain in the tunnels. A recent re-viewing of Ridley Scott’s Prometheus reminded me that tunnels and caverns in films often feature water drops that are drenched in heavy reverb. I pressed the “record” button in several settings and closed my eyes: Was I in the bowels of an ancient spacecraft? The Mines of Moria? The hull of a leaky, empty freighter?
The gun emplacement at Construction 129. No weapon was ever installed.
Occasional wind blasts forced me to enable a high pass filter at 120Hz to try to remove some of the ambient rumble that didn’t help the recording. In addition, there are no fewer than three foghorns in the Marin Headlands, so I had to make an edit every 50 seconds to eliminate the lonely bleat of the Point Bonita lighthouse horn.
There is always something worth recording. You just need to let your disappointment go, reset your expectations with some beginner’s mind, and just start rolling.

The Uptown, Mission District, San Francisco. Photo source unknown.
The Uptown is the closest bar to my office, and is a classic Mission District hipster dive bar. One hot, Indian Summer day in the fall, it was filled with patrons, windows flung open…but the jukebox was off. And everyone was concentrated by the bar and front door, leaving the back area empty.
Anyone who tries to record diffuse crowd sounds, or “walla,” knows that this is a golden moment. Human voices, but little intelligible conversation, no background music, not too far away from the noise source. I ordered a beer, sat as far away from everyone as I could, and started rolling on my handheld recorder.
I did a little trickery by taking a segment of the recording, swapping the left and right channels, and layering it with another segment, to effectively double the number of people in the room. Luckily there wasn’t too much background noise to also get multiplied. Perhaps not the most interesting of moments on its own, but the little details of the cash register ring, squeaky door hinges, and the general density of the human sounds represents (to me, anyway) a surprisingly hard-to-capture scene without the intrusion of music.

Battery Yates, Fort Baker, Sausalito, California.
Over a year ago, I posted some scraping metal sounds from the steel doors of Fort Baker’s Battery Yates, right at the Golden Gate of the San Francisco Bay. I recently unearthed some metal hits from that same session: They’re heavy, resonant, and the concrete rooms behind them certainly lent the sound some nice air in the low end. (Read the previous installment if you want to learn more about this location and how it was recorded.)
And, since today is Halloween, the original sounds are presented in both their original form and pitched down by an octave for extra heaviness and spookcreeptacularness.
Enjoy the clanky, boomy fun…and happy Halloween!

Look carefully: Deep impact zone, short period, wind parallel to the shoreline. Not a good day for recording single waves. So...what is?
It’s easy to get recordings of roaring surf – which can often just sound like constant white noise – but it can be tough to get relatively clean recordings of individual waves. I’ve found that picking a good day and place to record single wave hits are a combination of marine forecasts and location, and that the size of the waves really doesn’t matter.
The only online article I’ve seen that mentions both field recording and marine forecasting has been published by Tim Prebble. In that excellent article, he describes finding gentle-surf days to record his amazing Seal Vocals SFX library. Sometimes finding those small- to moderate-swell days are sometimes the best days to record single wave crashes…but that’s not the only factor.
Single-wave recording conditions are largely defined by a mix of swell, wind, and location.
Swell is due to the large movements of water over great difference; swell is not the same as waves, which are usually wind-driven. Swell is usually forecast based on buoys offshore, and is forecast days in advance. However, I find that 2-day swell forecasts are the most accurate. Swell is defined by wavelength and amplitude, just like audio: Wavelength is is measured in seconds (usually called period), and amplitude (usually called height) is based in feet or meters. Ideally, you want swell with long periods, because that means there’s a greater volume of water moving, but tall swell is also your friend, because that also influences breaking-wave heights at the shore. (Tip: Waves come in “sets” of big and small, between 3 and 8 waves each, depending on if there are multiple wavetrains that are in or out of sync. That means record for far longer than you’d otherwise think in order to get a good range of big vs. small waves over time.)
Getting back to the topic of wind, not all wind is bad (and we all know what wind does to field recordings: huge amounts of badness.) Offshore winds (those that come off of the shore – yes, that is totally confusing!) will might wave faces up longer than they’d be up otherwise, causing a moment of quiet before the wave breaks (or “closes out,” in surf parlance) and a potentially taller wave face. Wind coming onshore (onto the shore from the water) often smears the wave tops and can cause premature toppling…not to mention the fact that the wind will be blowing directly at your microphone capsules. (Tip: You can’t be at the shore without shorebirds, often noisy ones. Bird feeding activity, and therefore noise, may peak before an oncoming storm. Watch the forecast and choose clear weeks with low-pressure days, when it requires more energy to fly, when possible to reduce avian noise. Gulls are complete bastards in this regard!)
Finally, this brings us to location. Some of this is taste: Do you want to record breaking waves against sand, or against rock? Very different sounds will come out of each; bigger crashes will happen on rocks as opposed to sand. But beyond that, know a bit about your location. What direction is the swell and wind coming from, relative to where you’ll be facing? How does the land curve around, creating refraction waves? What is the slant of the land below the shoreline? This last one is especially critical, as the gentler the slope, the bigger the wave. The “impact zone” – where the waves actually break – can be deep or narrow, and a narrower impact zone will generate fewer audible breaking waves at once. Knowing if a beach has a “dumping break” is useful: It makes it terrible to launch from or surf near, but that also means the waves break right at the shoreline, which is far better for audio recording. Just watch out for your gear. (Not a tip, but trivia: Waves always break when the water depth is 1.3x to 1.5x the wave height, as the horizontal energy of the swell gets forced upwards to create breaking-wave heights near shore.)
Never turn your back to the sea. The sea is huge, powerful, indifferent, and above all, unpredictable. Rogue and “sneaker” waves are not legends or myths: They occur regularly, anywhere in the world. Don’t let a recording session end in tragedy.
A final note on technique: If you’re on a beach, angle the mic a bit more downwards than you’d think would be wise, and you’ll get nice sounds of the sand being pulled back as the breaking waves recede back into the ocean. Not always good to have in every recording, but this adds a lot more character. On a beach with fist-sized rocks, this can be especially cool!
I had a recent session at a sandy beach in the Point Reyes National Seashore that exemplified some of the better (but not quite perfect) conditions that I describe above. First, the wind was blowing at 20 knots…but from the opposite direction of the beach I was on, which was backed by hills. That meant delayed wave breaks and being protected from the wind. There was a southerly swell that came right into the dumping-break beach (I can tell the period is averaging 14 seconds by looking at the waveforms of the audio!), so it was all breaking swell and no wind-driven waves. It was a low-pressure day with a long-term clear forecast, and it wasn’t winter, when the masses of migratory birds come through Northern California. Only one swallow’s call made it into the recording.
The recordings aren’t all that dramatic when you consider the breaking waves were only 3-4′ high. But listening to this loud on headphones, eyes closed, I find that the sense of scale is quite exaggerated without an accompanying visual reference…a little Waves LoAir or layering some low-frequency booms can definitely can tip it into cinematically-big breaker territory if desired. However, even in a 90-second clip, there are only three really distinct wave “claps” as the bigger waves close out at the beach.

There are lots of under-the-radar software toys out there for mangling audio, but one that I have yet to hear anyone really discuss much is Spongefork, created by Ryan Francesconi over a decade ago. It’s been around for a long time, and is intended as a live improvisation instrument. Its incredibly sparse interface belies a lot of sonic mangling possibilities, with multiple sample banks and a live-control XY controller. For $65, it’s a fun toy. (Even the demo fully works, just without the ability to save work.) Heck, I’ve used it so long that I upgraded when I made the move from Mac OS 9 to OS X!
Here’s a set of live tweaks to some sheet metal hits (recorded when we had a custom heat shield fabricated for our wood stove). In my library, when I see “forked” in a filename, I know it’s gonna get weird…

My mecca on a foggy morning: Urban Ore!
I went to the granddaddy of thrift stores recently, so much so that it’s more of a glorified junk store…but oh, what glorious junk. I’m talking about Urban Ore in Berkeley, California. Sometimes I’m self-conscious shopping for things by ear, picking up random things and just listening to them, but at Urban Ore – heck, Berkeley in general – I can ear-shop in peace.
I was in a metallic mood, so I filled a bag with things that squeak, resonate, creak, clank, and sproing. Based on the dronetastic results of striking wire shelving last year, I picked up a few thin-wire metal grills that had sonic promise, among other things that will surely find their way to this blog later this fall and winter.
For the grills, I decided to trot out my much-neglected piezo contact microphones. The resonant notes were so subtle that it seemed like the best way to capture the sound at a reasonable volume. I plucked them, struck them, and played them with a cello bow. The magic happened, though, when I realized one was easily played with a bow and the other was not, so I stuck the bowable one inside of the other, and played away, causing both of them to resonate when played appropriately.
The results were like ultra-low-fi bastardizations of stringed instruments played in horror movies, and I just loved the character. The rawness of hearing the actual hairs of the bow on the metal, in my opinion, lends to the eerie charm.
