Single input two volume controls JTM45/Plexi

Post by Homebelly » Sun Sep 17, 2017 5:19 pm

Just wondering if it is possible to have a single input and still have fun jumping the channels?

Thinking it could be put onto a couple of switches maybe?

I found the older thread, but it has lost it's attachments during the change over to the new forum host/server.

You sure can. I have a diagram somewhere, using one switch for three positions. I'll try to find it and post it for you.

Wire the input to both channels. Then use a three-way on-off-switch to mute each channel at the wiper of the volume pot. Center position (no mute) will be both channels.

Another option is to use a two-pole on-on-on switch where each pole connects/disconnects the volume wiper to/from the mix resistor. Center will have both channels connected.

some just wire the input to both grids and then just adjust the two vols to get the desired mix.
