Newbie needs help!

[VintageVenzi]

Hey guy, I'm new here obviously to build my own stompbox ^^
I stumbled across the Valvecaster on the net and I have enough knowlegde how to build/solder ist but I'm lacking the knowledge for the details :/
As I'm bass player (Rickenbacker 4003 with 12kOhms pickups) I don't think the this setup will be the best tonal one http://www.beavisaudio.com/projects/ValveCaster/ and as the search wasn't so lucky I wanna ask you here what parts should i change to make it bass-compatible? Diagrams would be very helpfull! Btw I wanna use it as extra pre-amp/overdrive pedal ^^

try experimenting with increasing the in/out (c1/c3) caps

C2 also. Coupling caps are usually geared to guitarists. Try 100n or 220n for C1 and 2 and 2.2u or 4.7u for C3

basically, if you double the size of the caps, it will drop the operating frequency of the circuit down an octave.

you may get lucky, and it will work out..you may get some oscillations, in that case, you'll need to dick around a little.

I love it when you get all technical, Jimi
