Small 4HP filter with astonishing sound and complete feature package.
HP40 is based on the new 2140 filter chip, which is an improved update of the legendary 2040 IC from the late 70ies. This results in a sharp and precise sound, stable tracking and and awesome resonance.
Despite its small size it is a "complete" filter package with CV ins for Cutoff (1V/Oct), Resonance and outputs for 12,18 and 24dB slopes. In combination with the LP40 (its Low Pass sibling) it makes for a great bandpass or notch.
