Now I´m pretty sure the layout is ok!
Hope someone will give it a go!

Well, that is an interesting circuit.

Transistor Q2-Q5 should be 2N5088´s, not 2N5089.. Typoo..

Thank you so much for this layout.i'm already gathering the parts now.I will try to have this built within a week or sooner.The demo i heard of this on youtube was a clone but wow it sounds really good.I'm pretty sure i have all the parts to get started.I have to wait on parts for my fuzzy firebottle build so i'll start this right away.again thank you.i'll poast results asap.

It's related to the DOD Grunge, and therefore, the Boss Metalzone.  I have a DOD Death Metal, which shares almost the same circuit as these others, and Metalzone mods apply.

I have this built but it wouldn't work,i studied the schematic more and noticed it needs 10k resisitor connected to Vbias and #1 IC pin 5 but that didn't work either so i tried the Vbias on pin 6 and it came to life.This kind of works,its very gated if you let a note ring out it cuts off after a few seconds.like its not biased correctly.so i figure ill post this up and see if anyone here can help?I will keep working on it in the mean time.

There is a problem for some reason on IC1 at pin 5 the audio stops there.I traced the rest of the circuit,the vero matches the schematic but for some reason i cant understand this circuit will not work.i switched the audio from pin 5 to pin 6 at IC1 then the circuit works but it doesnt sound right to me? I'm going to move on to my next project.ill check back here if anyone has any questions i may be able to help answer?sorry guys
