This upgrade consolidates Softube's officially licensed Tube-Tech emulations into a comprehensive processing suite. If you already own the PE 1C and ME 1B equalizers, this path grants access to the updated CL 1B Mk II optical compressor, the Classic Channel Mk II, and the newly added SMC 2B multiband compressor.
The collection's foundation rests on passive, tube-driven signal processing. The PE 1C and ME 1B deliver authentic Pultec-style equalization with the harmonic coloration characteristic of transformer-coupled, all-tube designs. These aren't surgical tools; they add presence and musicality rather than clinical correction. The CL 1B Mk II remains one of the few convincing optical compressor emulations available, capturing the program-dependent behavior and smooth gain reduction curves that made the original hardware indispensable for controlling vocals and bass.
The Classic Channel Mk II, updated in 2018, combines compression, EQ, and saturation in a single strip - though with less surgical precision than modern channel strips, favoring tonal warmth over flexibility. The SMC 2B represents the collection's newest addition: a three-band opto compressor offering considerably more control than the single-band CL 1B, useful for genre-specific tonal shaping without reaching for multiband processing overkill.
This collection appeals primarily to mixing engineers valuing cohesive, analog-derived coloration over transparent processing. The vintage character works particularly well on rock, pop, and soul productions where saturation and compression warmth enhance rather than disappear into the mix. Sonically, Softube's emulations rank among the most credible Tube-Tech representations available, though users seeking pristine dynamics control should look
