I started out my bass playing (1969) with the wonderful Fender Bassman (mine had a blond head and the cab had the metal supports for angling). When I played my Tele, or my Les Paul, I found it delivered a unique clean tone for blues, R&B, and some of the early rock stuff. The tubes (6L6's if memory serves me correctly) made both, humbuckers and single-coils sound great. It ain't a Marshall, but the Fender Bassman was used in many recordings and live performances by countless guitarist of the era.
