This is our state of the art Tube Compressor. After years of painstaking development, Signal Audio Workshop is proud to introduce the Gainrider. An all tube, Class-A, Dynamic Range Controller, Stereo Limiter and Compressor.

Inspired by the early tube compressor topologies like the Fairchild 670 Tube Compressor (valued at $30,000) we decided to embrace the variable bias topology as our signal path with pure tubes and transformers circuitry and no solid state components in the signal path. We combined these early giant compressors signal path topology with a new, up to date control mechanism for the side chain.

Our side chain psyco-acoustic approach features conventional Attack and Release functions working alongside intelligent Crest Detectors that respond to complex music signals and not just the global levels, riding fine nuances in music like our ears do.

The M.S (Mid Side Compression) is an extra feature that encodes stereo information to separately treat the center and sides information of a stereo signal.

The Gainrider tube compressor is handcrafted with unprecedented attention to detail both internally and externally. The compressor features an embedded black panel with shimmering internal lettering and smooth gain reduction display.
