This amp had been modified slightly, mostly in the reverb circuit. This may have been done at the factory. I put the reverb circuit back to the stock circuit designed by Michael Soldano.
I also converted the amp into a Soldano SLO, which included: increasing the power supply capacitance, adding a choke, making some minor preamp adjustments, and adding a resonance control to the front panel. I moved the indicator LED over near the volume controls and added a bright switch to the overdrive channel - the "Warren Haynes" mod.
