Ian is right. I use a 147RV, and it has an adjustable reverb, adjusted with a push rod, instead of a knob. Really makes a difference when I use it with a Leslie pre-amp to play guitar through, or a keyboard without a 13 pin connector. Also have a 145...same unit, power-wise, but shorter and no reverb. Extra height on 147 RV is for extra reverb amp and spring chamber.

Nothing like it!
