Carcass fuzz - switch is very subtle

[neiltheseal]

Hey everyone.

I built a carcass fuzz which sounds great but the switch is just very subtle. Have I made a mistake or is this a common experience?

I breadboarded this thing this afternoon and the switch is also pretty subtle. One mode has more bass and the other a higher pitched and a bit filtered. but not enough of a difference to justify a switch.

Should I keep troubleshooting or are both modes on the carcass very similar?

I don't know, but mod for it by Chuck is here:

Also known as the PedalPCB Carcass Fuzz.
This beast is everything people say it is. Quite the range of tones. Something for everybody, I suppose. I built it to stock specs, except I used 2N2222s for Q4 & Q5. Believe it or not, there's nothing that I want to change. As described in the manual, BEFORE acts as a Gain control and AFTER acts as a kind of Bias control. Maximum gain on the AFTER control happens around 2:00. Both positions of the DEMHI/HALI switch work well with my Tele. I'm looking for the "Spirit in the Sky" setting. I think DEMHI mode, with BEFORE set low and AFTER set...

I built one and if I remember correctly it is what I would call "noticeable" rather than "subtle." I will dig it out and check. Also at the time I compared it with Carcosa video demos on YouTube and it operated pretty much exactly like the Carcosa. Maybe take a look at one of those and see if yours is sounding the same.
