Based on a rare and elusive circuit, the MXR Sugar Drive Pedal provides a diverse range of clear and transparent overdrive tones, from sauced up boosting to blown-tube distortion.

The key elements of that circuit design are the Drive control and something called a voltage doubler. 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 voltage doubler increases overall headroom, which opens everything up nicely.

It is amazing how MXR cloned this rare pedal circuit !

And they added a very effective buffer to it as well, but if you prefer, you can bypass it !
