Softube has introduced a new Empirical Labs series plugin that delivers everything from warm, gentle saturation all the way to forceful, explosive character for drums, vocals and more.
Professor Punch-Knuckles brings the highest degree of ELI saturation with three distinct types of modeled distortion/saturation: Toasty, Crunchy, and Distress.
Toasty and Crunchy are based on the saturation and preamp distortion of Mike-E. Distress originates from the compressor circuit of the Distressor and Mike-E. The easy-to-use interface is the quickest way to take your sound from warm vintage tones, through gentle breakup, all the way to the classic distortion/compression sound of the Empirical Labs Distressor.
Professor Punch-Knuckles features
- Three classic saturation flavors.
- The distortion sound of the Distressor.
- Tone shaping options including emphasis filters.
- Easy-to-use and instantly gratifying.
- Available in Flow® Mixing & Complete Suites, the new Empirical Labs Complete Collection 2, and as standalone plug-in.
- Console 1-ready.
Regularly priced 129 USD/EUR, the Empirical Labs Professor Punch-Knuckles plugin (VST/VST3, AU and AAX) is on sale for 99 USD/EUR at Softube and from distributors such as Plugin Boutique and AudioDeluxe until November 6th, 2025.
The plugin is also part of Empirical Labs Complete Collection 2 (alongside LilfrEQ, Mike-E Comp and Trak Pak for Console 1), which is on sale for $199 USD instead of $349 USD during the promotion. Upgrades and crossgrades are also discounted.
