Rob:

Read through the posts and is this pedal more metal than blues? Some of your earlier sound clips, page 1-2, are dead links and what I have listened to later sound more in the metal genre, and it does sound good.

I am interested in building the pedal, but I would like to hear blues tone oozing from your pedal  icon_mrgreen

Damn... everytime I blink my eyes you guys have a new mod..! Any audio clips of ver.4 yet? I have built a couple of these now and I still like ver.1 the best... I don't mind the extra switches because I usually just jumper two of them the way I like and use one switch anyway so no biggie... Version 4 looks interesting Rob, care to do a clip? icon_lol I really dig yer playing and it gives me a real good idea of what type of tone and sound I will be able to dail up...

If it sounds good, then it is good...

@textstrat, here is a demo of v3...check it out from 4:18..with volume backed off it cleans up nice for bluesy/funky stuff..

but you can get that by just turning gain down ok... Wink

Newark/element14 sell these for around $5. One side switches then the other side switches, the two poles don't switch at the same time.
Just another option...

Hmmm.  Just looking at the schematic on page 1 and C7 - 2.2nf seems too small to do much but add hiss.  I wonder if it is supposed to be 2.2uf, or .22uf or 22uf, all of which would boost things with various levels of bass???  Wink

Figured it out. I take an on-off-on SPDT and put the caps on the switch, not at the pcb.

Middle will be 3,3 and left 1,5 and right 6,8. This will give 4,8/3,3/10,1

If C7 isn't at least 220n, I'm not sure you can here it's contribution.   Shocked

; while hacking the spit 3, ive decided to go with 3.3n for the metal modern, its just that bit tighter...and 6.8n for classic..
