Finally got the build documents, which weren’t really needed, since the component values are printed on the pcb. There was a lot of chatter on the various guitar pedal sites about changing the value of the 92k resistor, just before the output pot, to a smaller value in order to get more volume out of the pedal, so I used a socket, so that I could try different values. It turns out that 92k is just fine (I actually used 91k). I also used a CA3080 instead of an NTE996 and it didn’t seem to matter. The compressor is reasonably quiet and can be quite “squishy,” if you pick you hard enough. It might have been nice to have both sensitivity and attack/recovery controls (there’s a 1M resistor feeding into the collectors of the pair of transistors in the envelope detector – using a switch or a pot here could have reduced the recovery time, thereby increasing the attack speed), but overall I’m very pleased with the compressor. The dark/normal/bright switch allows you to easily change the character and that bright setting really does give you a “jangly” sound, especially on single coil pickups. I especially love the sound when playing the lead to “Nowhere Man” – nice pedal.

This pedal is a lot of fun, especially in the ‘bright’ position. Definitely delivers what it promises. If you build it, the jangle will come.
Previous review mentioned the 92k resistor. I really don’t think it matters much whether it’s 91k or 92k, but I did decide I’d test just a few 1% 91k resistors and put in whichever came closest. The first one I tested was 92k on the nose, so it shouldn’t be hard to do if you’re exacting about such things.

Wonderful compressor. Was able to fit this in a 1590B and add an additional 3-way switch toggle 3 different caps on the bright setting.
