Kilpatrick Audio K6501 Philter Eurorack Module

Kilpatrick Audio K6501 Philter is a multi-mode filter module inspired by Kilpatrick Audio's Phenol desktop synthesizer. The two most often praised features of Phenol are its filters and envelopes.

Offering fat, punchy sound and dirty overdrive when the resonance setting is high, K6501 Philter is redesigned to work with eurorack systems. It offers low pass, band pass and high pass outputs simultaneously. Each output has its own signal indicator showing when that output is active. K6501 Philter has the same tone and range of control as Phenol's filters in a compact package.

Although it's only 8hp and looks quite tame, don't be fooled: the sound and tone color are completely massive. K6501 Philter will take even the tamest sounding oscillators and make them completely explode. Try it with drum loops and other sounds, or just run your whole mix through a pair of them!
