As a player and novice amp builder, I finally have no need to build or search any farther for my tone. My favorite amp is a Sunn Sceptre head that Richie Hall converted to a "Plexi" circuit for me. My favorite thing to do is to combine the Sunn head with a 1965 Blackface Showman head w/Fulltone & Analog Man pedals along with a 1968 Fender Vibratone for chorus. I seem to be able to achieve anything I want with this rig, no matter what guitar I use! Love ya Richie...may all your children be born buck naked! Peace
