Description
ThrillseekerVBL by Variety Of Sound is a variable-mu vintage broadcast limiter modeled after classic 1950s tube-based gain control circuits. Rather than acting as a brickwall limiter, it operates as a musical gain-structure leveler that smooths dynamics with warmth and harmonic richness.
The plugin goes beyond standard variable-mu compression by providing detailed control over tube amplifier harmonic distortion. Applied subtly, this adds analog warmth that digital mixes often lack; driven harder, it produces musical saturation suitable as a creative effect.
What sets ThrillseekerVBL apart is its transformer simulation, which models the frequency-dependent and load-dependent behavior of a real transformer-coupled tube circuit. This was achieved through developer Herbert Oeler's proprietary Stateful Saturation technology, which allows the plugin to model circuits with short-term memory rather than relying on simple waveshaping.
The result is a compressor/limiter that handles gain riding with the smoothness and character associated with classic hardware units. Users consistently describe it as sounding musical no matter how hard it is pushed, making it effective on individual tracks, buses, and full mixes.
ThrillseekerVBL is available as a 32-bit VST plugin for Windows, with a download size of approximately 2.66 MB. A 64-bit successor, ThrillseekerVBL mkII, is also available from Variety Of Sound.

Frequently Asked Questions
What does a variable-mu compressor do?
A variable-mu compressor uses vacuum tubes to control gain reduction, resulting in a smooth, program-dependent compression curve. Unlike digital brickwall limiters, variable-mu designs respond slowly and musically, making them ideal for gentle gain leveling and adding harmonic warmth rather than hard peak limiting.
How does ThrillseekerVBL compare to ThrillseekerVBL mkII?
ThrillseekerVBL is the original 2013 release available as a 32-bit VST for Windows. The mkII version, released in 2022, adds 64-bit support, independent control over saturation and compression, reduced CPU usage, and additional visual feedback. Both share the same core variable-mu design philosophy.
What is Stateful Saturation technology?
Stateful Saturation is a proprietary modeling approach developed by Variety Of Sound that simulates analog circuits with short-term memory. Unlike standard waveshaping, which processes each sample independently, Stateful Saturation accounts for how real transformer-coupled tube circuits respond differently based on recent signal history, producing more authentic analog behavior.
Can ThrillseekerVBL be used on a mix bus or master channel?
Yes, ThrillseekerVBL is well-suited for bus and master channel use. Its gentle variable-mu compression and transformer saturation add cohesive warmth and subtle glue across a mix. Many producers use it as a character bus compressor rather than a peak limiter, keeping settings conservative for transparent gain leveling.
