Project overview

The Xanthus Buffer/Boost is based on the Xotic Super Clean Buffer and Super Sweet Boost, two mini pedals that were first released in 2019 and traced by Aion FX in 2024.

The Super Clean seems to have been the first of the two to be developed. It has a decent amount of boost on its own, but Xotic seems to have quickly realized that it was easier to market them as two separate tools by making a few tweaks and calling the second one a boost instead of a buffer. But under the hood, the only difference is a single resistor and the value of the Gain pot.

The Xanthus is a hybrid of the two pedals, adapting them into a single circuit that can cover both modes. We added a toggle switch to go between the two versions of the pedal, adding gain and changing the EQ slightly in Boost mode.

We also converted the internal DIP switches to external toggles so they are conveniently available from the top. As with the original, the Xanthus also has an internal slide switch to select between buffered bypass and true bypass.
