Title: Hoffman Plexi 50 hot gain
Post by: Beezerboy on March 25, 2017, 02:15:37 am

thinking about building this one with the hot gain, but put it on a relay with a foot pedal instead of a switch. seems like I would be good to control how much gain you get when V1B kicks in. just put a pot between C3 and the relay.... or pin 7, or ????

I personally would want a pot before and after the hot switch gain stage.  Having said that, you could put one pot on the board inside the chassis or on the back of the chassis.
