The MXR Dyna Comp that was produced in 1976 has long been regarded as the ultimate stomp box compressor. There's something inherently musical in the way it "tightens up" a guitar signal, raising the volume of quiet notes and leveling off peaks to create rich, full bodied sustain. And now the MXR Custom Shop brings back that highly sought-after sound with the '76 Vintage Dyna Comp. Meticulously researched and superbly crafted, it features the exact same circuitry used in the original 1976 Dyna Comp, identical in its component layout, silkscreen and handmade wire harness. The key component is the old school CA3080 "metal can" integrated circuit (IC), which yields quieter operation, greater transparency and increased dynamic range. These ICs have been out of production since the '80s, but MXR has tracked down a stash of themenough to produce a limited run of these little red boxes of compression bliss. With supplies limited, the MXR '76 Vintage Dyna Comp is destined to quickly become as ultra collectible as its noble ancestor.
