Circuit-style passive program EQ. Tube and transformer colour. The boost-and-cut interaction, built into the topology.
Most EQ plugins start from a curve. TheTrick starts from a circuit-style topology. The passive network runs as a Wave Digital Filter tree, sample by sample, with resistors, capacitors, inductors, and frequency-selector switches represented in the structure. The tube makeup stage and transformer voicing are handled separately and remain in the signal path, so the colour is part of the plugin's identity.
Eight EQ controls. LF Boost and LF Atten share a four-position frequency selector (20 / 30 / 60 / 100 Hz) but drive two independent LC networks. Turn both up at the same frequency and the circuit produces a resonant peak followed by a dip: the boost-and-cut interaction that named the plugin.
The HF section has two independent networks. HF Boost is a resonant RLC peak with a 7-position frequency selector (3 – 16 kHz) and a Bandwidth control. High Cut is a shelving cut with its own 3-position selector (5 / 10 / 20 kHz). Boost at 10 kHz while rolling off at 20 kHz for high-end lift without excessive top-end bite.
The passive WDF section is linear, while the tube stage is handled separately. Dry/wet Mix includes a latency-compensated dry path for parallel EQ colouring.
TheTrick is offline-first. No activation, no license file, no telemetry, no phone-home, and no account dashboard. Download it, install it, and use it.
All current and future plugins in that bundle. Updates included for life. Prices rise as more plugins are added.

LF Boost and LF Atten both up at the same frequency. Two independent LC networks create a resonant low-end lift followed by a scoop above it. Bigger bottom, tighter low-mids. The move behind the name.
HF Boost at 10 kHz with High Cut rolling off at 20 kHz. The resonant boost adds presence while the independent shelf tames everything above it. A useful top-end move.
Even with all EQ controls off, the signal passes through the tube makeup stage and transformer voicing. Subtle even-order harmonics and low-end weight remain part of the signal path.
LOW BOOST and LOW ATTEN share a single low-frequency setting, creating a resonant lift followed by a complementary dip in the low-mids. The classic program-EQ move, built into the topology rather than faked with two opposing digital band filters.
Circuit-style modelling colours the signal path with tube saturation and transformer-inspired behaviour that responds to input level. It is part of the signal path, not just a static EQ curve.
Switch between Stereo, Left/Right, and Mid/Side operation from one control. Internal Mid/Side encode/decode and Lane Link let you move quickly between classic stereo polish, independent dual-lane work, and width-aware tone shaping.
The Trick is free, with the same modern workflow features as the rest of the line: Stereo, L/R, and M/S routing, Lane Link, parallel Mix, Auto-Gain, and always-on 2× oversampling. No account required, no demo limit, no upsell.
