From the post
There was some controversy over this pedal from Fulltone as the circuit is practically identical to the Jack Orman Mini-Booster. Fulltone no longer makes this version of the Fat Boost and now makes a 4-control version with an extra FET stage and more EQ controls. Regardless, it's a great pedal for beefing up your tone.
The perf and PCB layouts are slightly different. I was able to give the components more breathing room on the PCB that wouldn't be feasible on perf.
