Mxr M294 Sugar Drive Mini

Based on a rare overdrive pedal circuit that has acquired a mythical reputation among fanatical tone-freaks, the MXR Sugar Drive Mini M294 pedal offers an extensive range of clear and transparent saturated tones, from light boosting to blown-tube distortion.
It’s the key elements of that circuit design are the Drive control and something called a charge pump. First, the Drive control on this pedal doesn’t just increase the intensity of the overdrive pedal : it starts with your clean signal and then blends it with the overdrive effect as you turn it up, replicating the smooth transition of an amplifier going from clean to dirty. The charge pump increases overall headroom, which opens everything up nicely.
You can choose True Bypass (default) or buffered bypassing.
