Five Free Plugins. Collect Them All.

Your new weekly audio obsession.

Meet Thunderbuss Mix, the first in a collection of five completely free bus processors. Vari-mu compression, rich tube saturation and a powerful brickwall limiter, all packed into five simple controls. Serious processing without the complicated nonsense.

Every week, another Thunderbuss joins the family: Mix, Drums, Bass, Instruments and Vocals. Five dedicated processors. Five weeks. Not a penny required.

Your collection starts now. Free. No account, no activation, no expiry.

VU meter

Watch the Limiter Hold the Line.

Switch the meter to VU and the needle reads output peak with 0 set to the -0.3 dBFS ceiling - with the limiter engaged, it physically can't pass 0. Flip to GR and watch the compressor work instead.

Built to Glue, Not Squash

One Knob. The Compressor Does the Rest.

Threshold is the only control - everything else is locked to a program-dependent vari-mu character, with automatic makeup so turning the knob changes the glue, not the volume. SC HP adds a sidechain high-pass so the kick and bass don't drive the gain reduction and pump the rest of the mix with them.

Saturation adds one more knob of color, level-matched so more Saturation means more character, not more volume stacking on top of the compressor.

  • Threshold - vari-mu compression, auto makeup
  • SC HP - keeps the kick from driving the gain reduction
  • Saturation - level-matched tube color

The Limiter That Doesn't Pump

A 5ms Lookahead. A Real Ceiling.

Most free limiters chase a transient after it's already there. Thunderbuss Mix's lookahead and hold window mean the gain is already down before a peak arrives, and a two-speed release lets fast hits recover to where the mix is actually sitting - not dive back to zero and pump on every one. An envelope-relative soft clipper ahead of the limiter shaves the tops off stray spikes so the limiter has less to pull down on each one.

The ceiling never moves: -0.3 dBFS, always - and the VU meter proves it, with 0 set right at that line.

  • Lookahead limiter - 5ms, with hold and two-speed release
  • Soft clipper - shaves transient spikes before the limiter
  • Peak VU - 0 = the -0.3 dBFS ceiling, physically can't pass it
