Title: Switchable dual effect
Post by: night-B on April 21, 2011, 11:45:00 AM
I'd like two mudbunny's muffs in one box. Is there a way to wire it in order to switch the boards so that there's only one board engaged at a time? I mean one switch to engage the box and one to select the pcb... ???
It would be a cool effect!

This is the same concept just with switchable a/b in/outs.

What is it you want to switch? Is it just the gain, or do you want to switch between muff types on the fly? There are easier ways than using two full boards.

I'd like to switch between a triangle and a russian muff  ::)

Ah.

In that case, you want to use an A/B switch to simply switch between the two board's input/output.

The other switch should simply be a Master bypass. Do that switch like you would normally do a true bypass switch but the 'circuit' is the second A/B switch.

So if I understood correctly I should use a 3pdt switch to engage the effect in true bypass, and a 2pdt to switch the input and the output of the 2 boards right?

2PDT if you want no LED indication, but a 3PDT if you want LED indication. Look up A/B switching at Beavis Audio, and you should be fine.
