 Available in head and 1×12-inch combo forms (as opposed to the Prosonic combo's 2×10" form), the Super-Sonic also features the pre-Silverface voiced clean channel paired with the cascading-gain drive channel as pioneered on the Prosonic.Absent is the switchable rectifier or facility to run the amplifier in Class A mode, but a two-channel EQ has been added to the clean side, as well as a "voicing switch" offering tones inspired by the classic Fender Vibrolux and Fender Bassman models.With a footswitch, this was essentially the same as having two distinct clean channels that shared the same tone controls.
