The Superdrive Series II 18 head is designed for the clubs and project studio. This lightweight two-channel EL-84 driven amp offers sparkling rhythm complexity with super sensitive hi gain articulation. The jewel in this amp is apparent when the power section heats up and the dual 84's are being pushed to the point of no return. There something to be said about getting the power tubes to act like a preamp cranked where the sag of the circuit is creamy and the hang time on the note is forever at your fingertip. The Superdrive 18 is voiced for modern vintage styles of music.
