The appearance of this old, weathered, and rusted Fender Bassman belies the way this amp performs.
Nearly the entire chassis is covered in oxidation, yet this amp sounds better than a new boutique amplifier.
Features of this classic blackface Bassman include 2 channnels:
(1) Bass Instrument with 2 inputs, Deep Switch, Volume, Treble & Bass control;
(2) normal channel with 2 inputs, Bright Switch, Volume, Bass & Treble controls.
