The Fender Bassman 5E6-A increased output power to 40 watts and refined the cathode-follower tone stack that would define the 5F6-A and its many descendants. Two channels, four inputs, and the warm bloom of the GZ34 rectifier make the 5E6-A a superb blues and rock amp that bridges the gap between the early tweed and the iconic late-tweed Bassman. Its immediate predecessor to the famous 5F6-A circuit is well documented and historically crucial.
