This amazing Guild Thunderbass head has been in my private collection for years with very limited gig use. The amp has been flipped inside the cabinet so the handle is on top and was completely electronically restored by Tom Boffa of Sound Electronic Service. New tubes, new caps and a new grounded power cord were all installed. This version utilizes two 8417 tubes so it is the high output version (and it’s a monster!).

This head is in good condition cosmetically but not perfect…worn tolex at the edges of the cabinet and the faceplate shows some wear. It does include a nice padded cover.

I prefer NOT to ship this head but if necessary, I can get it to a UPS store (buyer will pay for their packing/shipping services). Pick-up is preferred and the amplifier is located in Colorado.

Please let me know if you have any questions.

Thanks for looking!
