The EHX Bassballs is an envelope filter with two separate filter bands (bass and treble) to provide a vocal quality. While some musicians like the simplicity of the single Sensitivity knob we offer a mod which adds a Sensitivity knob for each of the two filters. This allows you to finely tune the vocal quality of the pedal.
The Sensitivity Knobs mod costs $35 and is available for the USA and Russian models, but not the Nano model.
The Frequency Toggles mod installs one toggle switch per filter which allows you to lower the center frequency of each filter.
Other mods include True Bypass and jack upgrades as seen above.
