BASTL InstrumentsHendrikson External Interface Module (Aluminum)


In Stock Available immediately!


The Bastl Hendrikson is an instrument interface and amplifier meant for use with external effects processors. The module features a mix output with controllable crossfading via dedicated CV input. When used with an external FX unit, users can achieve remote control over the signal’s wet/dry mix.

As an instrument amplifier, the Hendrikson’s mix out functions like a traditional VCA, offering a clever means of creating tremolo-style effects when used in conjunction with the Mix CV in.
