Title: Blues Jr Hoffman Circuit Adding Reverb
Post by: ALK2MT on January 21, 2026, 10:42:26 am

I have a question about connecting the solid state reverb circuit back into the Blues Jr Hoffman circuit. I am wanting some expertise on modding the circuit. Could I just attach the reverb circuit back in on either side of R18 like the original circuit? How do I delete meat control as well.

Thank you!

Alex

You would also need to create a low voltage power supply for the IC to power to Reverb circuit.

The meat control can be deleted by simply not populating it and replacing it with a wire. Refer to the official Fender schematic.
