The REVERB-O-SONIC COMBO is a rugged, compact, and versatile two-channel 2×12 combo. Two 5881 power tubes provide 50 watts of power to drive two USA-made Eminence 12″ Legend V1216 speakers. The REVERB-O-SONIC COMBO is capable of creating a wide variety of sounds; from super-glassy Surf tones, rich, warm Blues edge to fat, gritty Classic Rock growl and much more – they’re all available simply by dialing in each channel’s independent Preamp gain and Master Volume controls. This 2×12 combo is extremely versatile and easy-to-use. Just plug in, dial a tone, and play – you can’t go wrong here! A footswitch is provided for effortless noise-free switching between the two channels. Bass, Middle, Treble, and Presence controls, as well as the tube driven six spring Reverb, provide the final tone shaping. Further tone enhancement can be had by utilizing the REVERB-O-SONIC’s tube buffered effects loop. This amp has two speaker jacks, so you can plug in an additional speaker cabinet if so desired.
