The Low Fat is a new 2hp Eurorack module by AJH Synth, it's a High Pass filter, with frequency control by either manual pot, and / or external CV with attenuator. It's intended to compliment other filters, particularly low pass VCF modules, in practical tasks such as removing excessive low frequencies, for example when the bass is swamping a mix. It can be switched between 6dB (1 pole) response and 12dB (2 pole) response.

By patching a CV signal to the FCV input it can be voltage-controlled and used musically as with any other VCF. When used in conjunction with a LP filter it forms a fully customisable band pass filter, allowing the range of passbands to be cherry-picked. Feeding in a 1V / Oct pitch CV and setting the FCV pot to a suitable level allows it to track an incoming pitch CV, so the amount of High Pass filtering remains constant as the pitch of the incoming VCOs traverse up and down the frequency range. This can be particularly useful in creating percussive sounds, such as snares and hats, but also on sequenced bass lines. Since it is only 2HP it's a great way to occupy one of those frustrating gaps in your eurorack modular case with something that is deceptively useful, and adds another dimension to the classic bass monster that is the Transistor Ladder Filter.
