Randall RK 500 HT 4-Channel Amp Used
These 300w solid state amp heads are quite uncommon and not a lot of info is available, but they are versatile amps originally designed for keyboard, with four inputs, each with gain, 3-band EQ and reverb control. The rear panel features 1/4in FX loop, pre out/power amp inputs, balanced and unbalanced direct outputs and parallel 4 ohm output jacks.
The amp is relatively compact and lightweight, with general light wear throughout. Good shape for its age (we believe this is from 1989)
