Includes:

• Variable-Mu Stereo Tube Compressor Limiter

From the Retro Gear Shop website:

"The Variable Mu Limiter Compressor is the GLUE that holds the mix together while crystallizing it into a professional, final product. All-tube, all transformer, an all-American legend. High Pass Side Chain mod now comes as standard.

The MS Mod turns the left channel into “middle” and the right into “sides” to compress each phase component independently. For example, squash the vocal, kick, snare, bass (in-phase info) while keeping the out-of- phase program intact to make the stereo image super-wide. The power switch must be relocated to the rear panel whenever the MS mod is applied.

The T-Bar Mod option is the ideal choice for routine extreme limiting, this mod makes the Variable Mu even smoother when pushed past 6dB of compression. Using two matched 6BA6 pentodes strapped as triodes makes this choice better than an unobtainable & unsortable 6386."
