Title: Installing a relay in the very front of a circuit?
Post by: hesamadman on February 22, 2017, 06:45:55 pm

The standard 2204 JCM 800 has the high and Lo gain input. I want to experiment with switching these. I've done it with a toggle. I can't think of anything that would cause an issue but can anyone think of where it would cause an issue to use a relay here so I can put it on a foot switch. Would just basically remove the second input jack and put it on a relay that (in basic terms) switch the signal from entering the first gain stage and the second stage. I may have to do a little more than this to completely make the first stage float. But before I get too far in it all thought I would ask for some thoughts

Just put the relay very close to the inputs so you don't have to run signal wires helter skelter across the chassis.

Thanks Sluckey. I'll give that a try.
