Introduction
« on: January 21, 2026, 10:05:12 am »
Good morning. I’ve spent the last 10 years building effects pedals and recently started working on amps.
I am currently building an Ampeg R12RB from scratch and pieces I acquired at an estate sale as well as a Hoffman Blues Jr. PTP build.

Happy to be in this group of knowledge.

Right off the bat, I do have a question about connecting the solid state reverb circuit back into the Blues Jr 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
