Info about the original pedal:

A compressor pedal incorporating the best attributes of classic pedals while simultaneously eliminating the shortcomings common to such vintage designs.

Included are controls for the adjustment of Attack, Release, and Ratio that allow the user precise and continuous variation to their sound. These controls offer the ability to custom tailor the effect to match the job at hand. No matter what style or instrument, the perfect amount of compression is easily dialed in with minimal coloration to the original signal.

Note:

The CA3080 is a discontinued IC, and although it is still available from a number of sources it will get more difficult to obtain as time goes by. After the discussions below, the circuit was tested by G5120fx with an LM13700 replacing the discontinued IC and it worked fine. Unfortunately this IC is 16 pin instead of 8 because it is 2 channel and includes buffers, but if you find that you can get the LM13700 cheaper or more readily then you can use the following daughterboard to allow you to use that IC. Just solder the wires to where the CA3080 pins would be on the main board.

This daughterboard can be used with any of the effects in this blog which use the CA3080, including the MXR DynaComp, Ross Compressor and Keeley Compressor.
