The unit is in excellent condition, but I can't get the reverb to work. The inside is clean, fuse good. I am not an electronics whiz, do I am not tackling the porject. It may only need a reverb tank. I am sure the right person can fix this and add it to their vintage guitar collection. This was taken in on a trade by my father in his music store so I am sure he thought it was repairable.

I have checked and plkayed a guitar through all the inputs, high and low impedence and all works.

Sold as is.

This is a rare piece. Do a search..I could only find 1 of these on the web and it was not for sale.
