Does anyone use a hot plate on their guitar setup? My guitar player has a Gibson LesPaul and a Marshall head (not sure of the Wattage) he also uses a 4 X 12 cabinet. He is having problems getting his sound to be "driven" enough and not end up being too loud. 1)-Would the hot plate help get more gain and saturation from the tubes, and bring his level back to a controlable volume? 2)-Or if I get a hot plate to use with his setup will make a big difference when we record?
