WORKING CONDITION: Excellent. All controls work flawlessly, and the reverb circuit is powerful on each channel. Both channels are robust and have individual Gain, Master Volume, and Reverb controls, with a shared EQ tone stack. This is a serious 90's fire-breather of an amp.

Does not include a footswitch

PHYSICAL CONDITION: Excellent. The logo, wooden case, chassis, tolex, faceplate, handle, and knobs are all in excellent condition.
