In the quest for ultimate tone, a compressor is an indispensable ally. And the MXR Dyna Comp that was produced in 1976 has long been regarded as one of the ultimate stomp box compressors ever made. There's something inherently musical in the way this compressor pedal "tightens up" a guitar signal, raising the volume of quiet notes and leveling off peaks to create rich, full bodied sustain. From country twangers to metal monsters, guitarists have long relied on the MXR Dyna Comp pedal to make their riffs stand tall in any live or studio mix.

Now the MXR Custom Shop brings back that highly sought-after sound with the '76 Vintage Dyna Comp. Meticulously researched and superbly crafted, the compressor pedal 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 them—enough to produce a limited run of these little red boxes of compression bliss.

The MXR Custom Shop '76 Vintage Dyna Comp effect pedal can be powered by one 9-volt battery accessed through the bottom of the pedal.

The Best... Period.

By Andy

from Sturbridge, MA

I first bought a MXR Custom Comp but than decided I would try a Dyna Comp Vintage '76 Script. As most of you know this is a "Holy Grail" pedal. In a shoot out the Script just had much more added clarity and less noise. I would highly recommend this pedal. I'm not much of a compression guy but this pedal I will not sell. Get it before it's gone for good!

Every Guitarist Needs This

By Josh

from Pelham, NH

I've never been a big fan of the MXR pedals, so for me to talk about how great this pedal is, is something in itself. This compressor never leaves my effects loop because it adds that simple little kick to my sound when i need it. It is perfect for every style of playing. I know this because i do use it for everything. Whenever I need jst a bit more out of my amp without completely changing the sound of my guitar I know i can rely on the DynaComp. It can add subtle sustain where you need and tremendous power when you dont, but just really want it. It mends into pre existing sounds perfectly so I never have to worry about losing the tone I'm getting from another pedal. It is simple to use only having two nobs. Every guitarists deserves to have one of these pedals, it's essential.
