Hi there pedal nerds!
In the last few days I finished my first ever vero build.

I wanted to start simple so I took a Tonebender MkII (Silicon version) schematic and sourced all the parts. For trannies, I used 2N3904 and BC550C (as a replacement for 2N5088).
Pedal works and it's loud, but there is a problem with biasing - sound is pretty gated, a bit too gated for my taste. I'm not sure if you want to see voltages for Q1, Q2 and Q3, if you need it I can post later.

Since the schematic doesn't feature trimmers to adjust the bias, can I somehow add it to the build? I have 5K, 10K, 50K and 100K trimmers laying around.

The link to the schematic seems to be broken in that thread

welcome to the forum. we want to see your layout, and photos of what you have built, and those voltages. please.

Guys, sorry for not posting for some time, I figured everything out.
