New to the board here. I just bought a VHT 50st, the el84 version. I love it! I'm waiting on a foot switch I ordered, a two button VHT reverb and channel foot switch. On the back of the amp there are two inputs for foot switches, reverb-EQ and drive-boost. Which of these should I use for the foot switch? My only desire is to switch between the lead and the clean channel, the reverb isn't as important.
