The whole thing fits on a 12x9 piece of veroboard and fits reasonably comfortably in a 1590a enclosure.
What a great pedal. It's a boost/OD pedal. It'll give you a nice tubey breakup on the clean channel and beef up your drive channel for leads or chugga chugga. I use it on a low gain setting and kick it in for an extra mode.
A pedal with this few components has no right to sound this good.
You can crank one of these out in an hour or two. The most time consuming part was drilling the holes in the enclosure and getting everything to fit snugly but once it's in there, it's a whole box of awesome.
I didn't follow the Zvex design on acocunt of me not having the precise components in my bag of leftovers. I changed the diode, the transistor, a capacitor, the pot, and left out the 2k2 resistor because I wire my LED clr by the switch (and use a 4k7 anyway), and it's what I had. As a result, I'm not sure how close this is to factory spec but I love it either way. It's way more useful than the Friedman clone.
Mids so haunting that demons took over my living room and now my guitar glows!
