Amp selector...

[Roel Das]

Hello again...

My friend bought himself an 1977 Orange amp. Very nice, but broken. Mean
clicks... We opened it up to check if it was one of those no-PCB designs (it
wasn't), and there was a big cap swinging aroung with one loose end. No idea
what I was doing exactly (Yes, somebody should really give me a spanking),
but it wouldn't hurt to just fix that cap, little solder and it's connected
to it's leads again. Lesser clicks, but still...

Anyway, he needs an amp-selector for this. A pedal, with guitar input, and 3
outputs, one for each amp, that can be switched on and off seperately. Maybe
I'll add a switchable effectsloop too as a bonus. Quite easy, some flip
flops, and fet-switches. The guitar signal will be going to 3 amps, worst
case. Should I put buffers in this(And offcourse, why, why not?), and how
can I get a buffer for this to work on a 9V battery? (No symmetrical power
source...)

Thanks
Roel
