If you're reading this thread you already know that the Gibson GB440 is the basis of the legendary Thunderfunk amps. I've had this amp for a couple of years and have not used it much. I'm more of an SWR guy. I sent it off to David Funk 3-4 months ago. He took care of a bad ground in the effects loop and re-biased it. As you can see from the picture it has the "TF serial number, so it is from the batch of amps that Dave assembled. I added the Speakon. More history on the Gibson/Thundefunk connection in the thread below. The amp ships in the original Gibson bag. Asking $400 or best offer shipped to the lower 48
