This pedal is a piece of engineering brilliance. Designer Stewart Ward designed this pedal as an update to the famed Jerry Donohue JD-10 Distortion pedals. If I remember correctly, only 200 JD20 pedals were produced.
This pedal is more than just a Distortion / Overdrive pedal. In addition to his patented Flexidrive Distortion (which I like to think of it as a "Marshall in a pedal"), the pedal also has a button for C12T Speaker Simulation Emulation and EQ that actually shapes and characterizes the sound (unlike most overdrive pedals I've used). If your amp dies during a gig, you can send the direct signal of this pedal to your PA System / Mixing Console and get great overdrive tone in a pinch using the built-in cabinet simulator.
I've tried dozens of overdrive pedals out there and I've always come back to Award Session, primarily using the JD-10, and the AP-10 for acoustics.
