XanthusBuffer/Boost

From the vendor

A dual-purpose pedalboard tool that combines a Pete Cornish buffer with a highly tweakable boost.

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.

Note: This project uses a type of capacitor that has been temporarily discontinued by WIMA. Please see our news article about the issue and the substitution spreadsheet for project-specific recommendations. We are stocking a limited supply in the mean time. The build document has not yet been updated to reflect this.
