Purple Audio MC77
The MC77 supercedes the MC76 re-engineered 1176 type FET Limiter. The MC77 recreates the audio circuitry of the revision E 1176, using modern components matched to the original.
Starting in 1997 Purple started making the MC76, an 1176 type compressor base on the D & E version units. (MC is 1100 in roman numerals) At the time the 1176 was not available from any manufacturer. Coming from the repair background it was clear a better built, more road worthy unit could be build and sold new for less than the 20+ year old units that were coming through the shop. After another manufacture brought an 1176 clone on to the market Purple introduced the MC77. The MC77 added new features that were lacking from the original. Thousands of units later Purple keeps its parts and build quality high. Using parts that will last decades. Have a look inside and see for yourself. Toroidal power transformer, the best interlocking switches on the market, conductive plastic potentiometers. Quality for longevity.

I have an original 1176 and the reissue and this is by far the best unit.
Noise floor is so low, smooth highs and focus mid.
It's my go too compressor now
