When I first started recording, I got an inaccurate understanding of compression stuck deep in my mind. I only really started to exorcise it a few years ago, and I still think the way compression is often explained is confusing. (Maybe I’ll post a follow-up on The Compression Conspiracy, or maybe it will come out here.) I’ll attempt to explain compression clearly and simply, touching on limiting and clipping along the way.

Compression is automatic volume reduction, or “variable attenuation” if you prefer. Compression is not soft clipping or peak reduction*.

* Peaks will be reduced in the course of automatic volume reduction processing, but since the whole signal is being reduced it’s confusing to call that result “peak reduction”

Compression is like having a gremlin enthralled to your instructions, whose hand is on a volume knob. You can tell the gremlin how fast to turn the volume down when your input signal gets loud (compressor “attack” time), how fast to turn the volume back up when the input signal gets quieter again (compressor “release” time), how loud is “loud” to you (compressor “threshold”), and whether you want your gremlin to turn down the volume a little, or a lot (compressor “ratio”).

The world of guitar (and synth, and bass…) modulation effects overwhelmed me at first, but I’ve learned that most pedals and plugins are based around just a couple of ideas.

	Time-based effects	Filter-based effects
Base version	Chorus	Phaser
Variations	Flange (chorus with feedback) Vibrato (chorus with no dry signal)	Uni-Vibe or “Vibe” (phaser with mis-matched filters)

Time-based effects are created by 1) copying the input signal, 2) delaying the copy by a small amount (a few milliseconds), 3) automatically changing the delay time (say, from 27 ms to 33 ms and back), and then 4) mixing the input (or “dry,” or “not delayed) and delayed signals together (typically at a 50:50 ratio). The resulting sound is a pseudo-doubling effect with a bit of pitch going up and down, some frequencies of the input signal enhanced, and others diminished. Boom; basic chorus.

Flangers operate on the same principle, with shorter delay times and feedback in the delay signal path (just like a delay or echo pedal), resulting in a more pronounced effect. Flangers with knobs for feedback amount are often great modulation pedals because they can cover a lot of territory from subtle near-chorus to crazy flying saucer flange.

Cory & Mike did some Halloween raps & beats, check ’em.

For my own future reference, here’s the status of my DS-1s. I switched the battery covers and knobs to get them back to “stock.”

On the left is my first pedal ever, circa 2001-02 for use in No Front with a borrowed double cut Les Paul Jr. and AC30. Cole performed the Casper Electronics mod and did the battery cover art around 2014-15, I did further Casper-related mods in 2016, and recently I put a tone stack mod on a toggle hidden in the battery compartment. This unit will live on the synth minirig board.

On the right is the “DS-1 lab,” my research platform and repository of all of my favorite adjustments, from 2016. It’s a studio piece for guitar, mostly.

Been working on pedals for the past few weeks while I write Fight Songs lyrics.

These are all one-off builds for my own use.

• V4 MV – Passive master volume control for my Ampeg V4 amplifier. Ampeg used to sell these as an accessory but they’re dead simple to make; a single potentiometer wired as a variable resistor. The amp is incredibly loud so this will help bring it partially under control
• DS-1 mods. This pedal is literally my first, from around 2002 (except for the battery compartment cover donated from the “DS-1 lab” unit). At my request Cole modded it years ago with the Casper Electronics gated feedback/oscillation mod. I added my flat + LPF tone stack mod, tucked away on a toggle in the battery compartment
• 404 M 2 ST – A passive mono-to-stereo passive pan box mostly designed for use with my SP-404 sampler. The 404 can record in mono or stereo, and has stereo effects, but doesn’t have any type of simple pan control to move things around in the stereo image. With this I can pan stuff as it’s being sampled
• R2-T2 – Breakout expression box for the Pigtronix Rototron rotary speaker simulator (which mostly lives with my Roland VK-1 organ). The footswitch and toggle engage the Brake function. The knob can be plugged into either the Low or High Rotor Control to defeat the on-board Speed control for that “rotor.” If it’s reminiscent of anyone’s favorite droid, well, that’s a happy coincidence

I finished guitars for Fight Songs last week, I think Friday night. The last few tracks were Motown-inspired guitar DIs using the setup below.

Signal path, from the right:

Pigtronix Philosopher’s Tone Germanium Gold Micro – Quite a mouthful for this little optical compressor. Picked it up used on a lark based on how much I’ve enjoyed the DOD 280 reissue, and the added blend and grit controls are nice additions.

Fulltone GT-500 – Haven’t used this in quite a while. As I was recording I decided I wanted a kind of cocked wah sound, but an actual wah was too much. The inductor-based mids control on the distortion side of the 500 was perfect cranked all the way up. Only used this for the EQ, it’s not doing any distortion.

I impulse-bought an Ampeg V-4 and matching speaker cabinet this week.

Price was bordering too good to be true, but it’s in pretty great shape considering it was built somewhere between 1972 and ’75.

I haven’t done any meaningful soldering since making last summer’s Thereatari, but I’m getting ready to. The other day I modified my Caroline Guitar Company Meteore reverb.

I always liked (and haven’t changed!) the sound of this pedal, but I had a couple problems using it: the sweep of the reverb volume knob made it hard to dial in the amount of reverb I want, and the “Havoc” switch went to instant oscillating madness when the size, regeneration, and gain controls were above about halfway.

To address the first issue, I switched out the stock anti-logarithmic “C” taper potentiometer for a linear “B” taper. No change in sound, but more fine control over low and medium reverb volumes.

Our own Cory Kibler and Mike Papagni are Van Ripper & Galactifader, a seriously funny and oddly poignant rap duo. You can check them out on Spotify below.

There’s no way to explain this music that makes it sound cool or real, but it is both. Mike is an incredible drummer, and Cory worked his way into bars that reflect his point of view without pretending to be anything he’s not or assuming any kind of weird affectation, and a delivery that manages to put a touch of edge into his dad jokes (“Extra Virgin” being Exhibit A).

I’ve been working steadily on guitars for Fight Songs, switching over from electric to acoustic a few weeks ago. I think I have six left, something like that.

Most (all?) songs are getting two guitar tracks to start with. Then I’ll add some shakers and tambourines and other percussion and get the mixes roughed together before doing vocals. At that point the question will be “What details will help this song?” and the answers will be different for everything, “None!” being a viable option.

Mic is an Audio Technica PRO-37, which I am absolutely loving. It happens to be a very affordable mic, but it sounds like a million bucks to me. To my ear is has a full-frequency, flat-ish response for a small diaphragm condenser, and most importantly the off-axis phase cancellation that’s an inherent aspect of condenser mic design is minimized. Really great.

I finished the Monotribe-based Minirig – quite a while ago – and have had some fantastic jams on it, though I haven’t recorded anything with it yet.

Long story short, there’s drums, two synth voices, two drones (Thereatari, DS-1), and effects. It sits in a sweet spot of possibility and limitation; there’s certainly enough to keep busy and make a full, if minimalist, track, but whatever I make with it retains a kind of smallness befitting the rig itself.

One of the design goals was to build something that could be used for solo performance, and I hope to give that a live test soon.
