## Description

The op-amp sound that put punch and harmonic density on decades of hit records — now on iPad and iPhone. Four musical bands, TREMOR sub, live spectrum. AUv3 ready.

P422 Fairuz is a four-band op-amp parametric EQ that moves past hardware — the punch and harmonic density of classic op-amp circuits, with capabilities the originals never had.

Shape your sound with HIGH, HI-MID, LO-MID and LOW bands, each with three selectable curves (Bell, Contour, Contour X2) and proportional Q: wide stays wide, narrow finds itself. LO and HI shelves with complementary dip behavior, switchable HPF/LPF, and the TREMOR circuit laying a sub-bass foundation below 30 Hz.

Character comes from the circuit, not just the curve: the VOICE input transformer control and HAMMER output stage add body, density and saturation — op-amp color available even with the EQ bands off. Blend it all in parallel with the MIX control, no DAW routing needed.
