The classic returns, first conceived by David Oreste Defrancesco (DODs namesake) in the 70s as a way to get distortion and boost without any of the downsides that came with some of the fuzzes of the era. This updated version uses the vintage correct LM741 OpAmp, just like back in the 70s. Modern appointments like a tough, light, pedalboard friendly aluminum chassis. standard power input jack, true bypass, LED indicator, and bullion gold powder-coat makes the 250 at home on any pedalboard.
