Rivera – Fifty Five Twelve Guitar Combo Amplifier w/ Ft. Switch – Used

The Rivera Fifty Five Twelve 50 watt EL34 powered circuit features two distinct channels and preamp sections.  One channel is Fender Blackface, the other is vintage Marshall Master.  And you get specific boost circuits for each channel.  And it’s all controlled with the footswitch.

These are hand wired in California by Paul’s team and feature 12AX7’s in the preamp, EL34’s in the power amp, and a solid state rectifier.  The Fender Channel can nail that Blackface chime, the Marshall Channel can take your head off.

This is a used amp in excellent condition!
