Mike, I'd try to put the trem part even after the first stage...I love this Vibracaster, but the best sounds are with the gain knob at its min. - don't like the distorted sound with the tremolo on...So it could be interesting to try to put it after the first stage, or just ditch the gain pot in favour of a fixed resistance, to give a small amount of gain or none, as Rick did if I remember correctly...
So I'd say you could have a 2 or 3 switches pedal, with
-1 or 2 stages at low gain and the trem
-2 stages (standard valvecaster)
-4 stages (twincaster)
Anders, glad you liked it, yeah there's a lot of wire to solder, I spent quite a lot of time just to find the best components' positions inside the enclosure, I ended up with the tube socket in the middle and the four knobs around - sure the wiring needed some more attention, but I just don't wanna think of my wiring skills let's say 6 months ago, it would have been a
spaghetticaster!!!
I'll post a couple of guts pics...
I think I am gonna build another one someday, but you know the BB size could help...
all the best and take care...
