Aion Modular904B High Pass Filter

Aion Modular 904B

If vintage highpass fizz is what you want, then fizz you'll get: Aion's high-quality clone of Moog's original 904B Voltage Controlled High Pass Filter provides the same performance as the original in an unprecedented footprint and price. Faithfully recreating the classic buzzing, zapping sound of the original, the 904B is a perfect way to add vintage Moog filter sound to any Eurorack system.

Note: the 904B opens up considerably when paired with the 904A Lowpass Filter and 904C Filter Coupler. Together, these three form the classic filter arrangement of many original Moog systems, complete with options for variable-width bandpass and band reject response, and countless other rich filtering effects.
