I bought this '67 Bassman head a while back and it had been modified with reverb and cascading gain channels. It sounded great but started to oscillate and feedback at higher gain settings. I gave it to a friend who decided to restore it back to original AB165 specs but he never found the time so it's up for sale to some adventurous soul to restore it, turn it into that fire breathing Dumble clone or part it out. The three transformers are original and work fine. The circuit board was modified and is now partially disassembled. It's sold as is and not working. Check out the pictures for details and message us with any questions. What you see in the pictures is what you get. Thanks for looking!
