Your vcl 515 Black Friday deal is Fuse Audio Labs' Vari Mu Limiter plugin at $19, 67% off, until Dec 6, 2026.
The VCL-515 is a plugin version of a rare 1960s tube limiter. The hardware was built on a push-pull feedback topology and designed for US broadcast.
It came to market with technical improvements, aimed at competing with the well-known 438 compressor of its day.
It applies soft-knee compression. The maker describes the effect as large yet relaxed, and says it sits voices and instruments into a track in a natural manner.
Fuse Audio Labs also positions it as a main compressor for the mix bus or the drum bus.
The tone comes from the original circuit's triodes and custom transformers. The maker says the warm sound of that circuitry is a reason to want the VCL-515 on its own.
The original hardware has essentially one control: an input gain that sets how hard the compression works.
The plugin keeps that and adds more for everyday use:
A mode switch lets you run the tube sound with compression applied or without it.
The tube saturation is meant to stay in the background. The maker describes it as a smooth, creamy thickness that glues tracks together.
Transient handling is gentle, and Fuse Audio Labs says the generous gain reduction comes free of unwanted artifacts.
In the maker's words, the result is musical compression that makes a difficult job easy.
The VCL-515 plugin runs on Mac and Windows.

Yes. The VCL-515 Black Friday deal takes 67% off Fuse Audio Labs' tube limiter plugin, bringing it to $19. The discount runs until Dec 6, 2026.
It keeps the original input gain, which drives compression, and adds variable attack, release and sidechain filter parameters. There is also an integrated mix stage with an output level control, plus a mode switch for tube sound with or without compression.
On Mac it supports VST2, VST3, AAX and AudioUnits, 64-bit only. On Windows it supports VST2, VST3 and AAX, in 32- and 64-bit versions. Your host needs to load one of those formats.
Fuse Audio Labs says it is modeled after a rare 1960s push-pull feedback tube limiter, originally designed for US broadcast. The maker describes its character as smooth and harmonically rich, suited to vocals, instruments and bus processing.
