Filtek Mk3

The Filtek MK3 is a three-band EQ plugin modeled after the classic 1970s broadcast hardware. Each band offers 12 selectable frequencies with up to 16 dB of boost or cut, plus a three-way Q switch that also bypasses the band in its middle position. High- and low-pass filters extend its range, and the parallel EQ path lets you blend the dry signal with an additional boost or cut for unique tone-shaping. Its transformer-based I/O delivers a clear, precise character that stays transparent when boosting highs—no added harshness—yet packs punch when pushed. Use it for surgical fixes, broad tonal sweeps, or creative experiments on vocals, guitars, drums, and full mixes. It suits hobby producers and engineers who want authentic analog flexibility in a plugin, running natively on Mac or PC or in real time on Synergy Core hardware.
