Ah so excited to finally see the inside of one of these bad boys and learn about the features that make up the tone of John's Signature Two-Rock amps! As a reminder, I publish these insights and thoughts for educational purposes and not to undermine, destroy, or promote in any sort of way. The information is to guide someone someone to learn to build this amazing, out of production, amplifier.
On the Dumble amp clones and D-style pedals Facebook group, a generous forum member who was working on a JM Sig for a customer (it kept blowing a fuse) provided some really nice gut shots. Because of my own quest for information, as well as a few other members on My Stupid Mouth forum, these pics help with reference points. There were a few prototype and post production "signature" amps that were let out into the wild which did not flip the preamp section and did have pictures taken of the inside to help the information flow along.
Some of my notes that I cover in the YouTube video
