I bought and refurbished one for the bass player in our band and he LOVES it as a bass amp. I rebuilt it stock and of course tried it for harp. ..... Not bad, not great. Not 50W loud for sure, and fairly clean. Sounds nothing like a model 1 or model 2.

If you happen to get one to play with I can save you one headache - the power tube height is critical to whether the chassis will fit in the cabinet. I tried several that were too tall! SO if you you have to replace the power tubes, be sure to buy some that fit!

Thanks Greg. There is one on CL that is really clean for low money. I sent the seller a message but no response. Not surprised by this, musicians seem to be very hard to do business with. Those amps have good speakers and huge transformers. I looked at the schematic, they do look to be low gain. No info on the web as to harmonica usage which leads me to believe they are not that great as you said. 6EU6 pre, hard tube to find. I think it would be a good project platform. Like I need another project...

Help, I'm Possessed. AAAEEEeeeah.............

Actually Goose, you can get a complete tube set for it from AES since the Gibson Thor Bass amp had the same configuration.

Hell, it might have been the same circuit too...

But a conversion for 12**7 type tubes would probably make it sound better anyways....
