Edited from an eBay listing that I found interesting with some great playing tips [cannot vouch for accuracy]:
The MXR Dyna Comp compressor (or any compressor for that matter) can be a misunderstood and underestimated effect. Think of compression like this — an overdrive does for your dirty sound what a compressor will do for your clean sound (harmonic boost/more clarity).
Not surprisingly the first genre of musicians to catch on to the value of compression were Nashville greats like Reggie Young and Jerry Reed who have used the Dyna Comp and Telecaster combination on many trend setting albums.
The key to getting those big tones from the Dyna Comp is the sensitivity control. This takes all of the less dynamic sounds such as:
- low output strings
- or the ‘pop’ of your pick and raises them to the same level as everything else.
The Dyna Comp does this with incredible clarity and infinite sustain. If you place the sensitivity level around two o’clock your big country style bends all of a sudden make sense and the notes simply hang in the air as long as your fingers are on the strings. When you combine this pedal with overdrive, chorus or delay the results can be truly inspiring.
