Tonite our singer-bass player/GC manager said this was the best of all th ODs ive brought in the last 6 months. He didnt kno it was a Mesa till he came close. ive brought a few- Landgraff, BBpre, RC Boost, TS808, Rats and Solo proco, Maxon OOD and OD9, Boss OD-3 and SD-1. Tone's subjective but this is a fine overdrive!
