2204 Relay Switching?
Posted: Sun Jul 11, 2010 6:57 pm
I have been told that it is possible to install relays that can select between two sets of preamp gain and master pots on a JCM800 2204 circuit essentially giving you 2 "presets" of the preamp and master. If anybody has this drawn up in a layout I would be most appreciative to see it. I am building another 2204 but I want to be able to swap between clean and dirty settings without having to twiddle the knobs in a live setting. I'll do another lengthy blog!
