This tribute to the GasPedals DumbBell V2 is a 2-in-one OD pedal.
Left footswitch triggers the effect, a sweet OD-Distortion, bringing all the classic Marshall-ish tone on your amp clean channel. Right switch triggers a Volume-Mid-Boost which brings your tone up to cut the mix. Don't expect too much control on the gain knob, the sweep is not very wide. The tone control brings a nice harshy trebly crunch.
Since the original is rarely seen on the used market (and when they are, it's over 400USD), a clone is really a good option here.
