Finally received my Gibson Reverb III! Not sure exactly what year it’s from, but definitely early-mid 1960’s. She’s solid state. Power knob, reverberation knob, hard wired pedal, hard wired output chord. The end. Simple simple simple. The springs sound killer. Also, it takes my pedalboard very well. I’m going to run it thru some paces at band practice in a few hours, and I’ll report back. This is the first Gibson item I’ve ever owned. Glad the money went to a friendly old Mainer, and not them! $125!!! Talk about a steal!
