Switching Question, 2 circuits - on/off - on/off and both on

[tskullt]

Hi everyone,
  I have a friend that wants a compressor and a screamer in one enclosure with three switches, individual on/off plus a switch to turn both on simultaneously.  Is there a way to do this with dpdt or 3pdt switches?  Thanks for your help.

frankly I would just put the two switches close enough together so I can whomp on them both at the same time!

Here is a way I've done it before. I also added in a loop send & return using 2 normally closed jacks. That way you could expand the master on/off by plugging other FX in the loop like a chorus or flanger. If nothing is plugged into the loop jacks the signal continues on & back to the master bypass switch.

The only foreseeable disadvantage is that the master bypass switch must be on for anything else to work. Another note: you could add another bypass switch for the loop send & return. Pretty flexible setup. TPDT switches are shown, but LED’s left off of clarity.
