With dual pairs of inputs, dual volume controls, and a range of tone controls, this is a versatile mid-range power amp, that is popular for bass as well as guitar. The warm tube sound from 2 6CA7 outputs and three 12AX7A’s for the preamp, worked just as well for guitar amps as it did for basses. Vintage Traynors are less high profile than other amp makes, but very good value.
