I kind of thought that's why the tone pot is 2k, r8 and r10 are keeping the 2k pot fixed within the useful range of a normal 20kW. But then, I'm just guessing...

Built it yourself, and if you have issues, debug them from the schematic compared to the veroboard layout.

I've got it wired up with that vero right now, just waiting to grab some toggles and I'll be able to confirm whether it is verified or not.

I had no luck with the vero layout, but I did up a dual layer PCB. If anyone's interested in a 2 layer board, I'll post it.

I built the vero of this and got clean sound only through it. The volume and tone controls worked but no response from the gain control or clipping switches. I haven't had time to look at it closer.

That was my experience as well.

Hey, guys. I'd love to get the vero layout sorted. I just double checked it against the schematic mostrummer posted (which is what I based this vero on) and it still looks correct to me. I also compared it to the GGG tube screamer schematic and apart from a few small changes the schematic looks good.

The only thing I can think of right now is that we don't agree on how the lugs on a switch are numbered. The vero layout is based on switch lug #2 being the center one and lugs #1 and #3 being the outer ones. Also, did you connect the center lug of the "Bass" switch to the center lug of the "Clip" switch? Without that connection R5 and C3/C14 would be taken out of the op amp stage and I guess result in unity gain only.

So can anybody tell me if the vero layout is good? Since I've read that a lot of people got problems with it, and it isn't verified.

FINALLY here is that dual layer board I used. It's verified. Don't forget to make the vias.

Thanks for the PCB layout, Barcode. :D But I noticed that it slightly differs from the schematics posted on page 3 of this topic. Which is the real one?

Verified my vero layout (page 4) today. I had to reorient the drive pot wiring, but otherwise it was working nicely.

Yeah, like the vero layout from earlier in the thread I omitted some of the .1uF caps that are unnecessary. Other than that it should match.

LAYOUT NOT VERIFIED - IT DOS NOT WORK

Hi
here is the layout for boiling point based on schem on page 3
I built it and it does NOT work
It seems ok to me but it does not work. It is quite as a grave, no sound at all (neither ssshhh or hum or anything else; absolute silence)
So can anybody take a look at the layout? Maybe i made a mistake in populating pcb but not sure
thank you
hot
