FROM BARBER ELECTRONICS:

In research and development, Barber studied the problems associated with classic guitar compressors and their recent clones and found that, while the clone-makers build pedals with improved components (cleaner switching, in particular) and matched transistors, a few of the major drawbacks of those “vintage” designs still exist. The most glaring drawback of popular classic compressors is that they reverse the guitar’s phase and cause a “pop” that squashes the attack at the beginning of every note. Although we now see some compression units that have attack controls, they leave a bit to be desired as they require seemingly endless trial and error tweaking , and still no true solution to gracefully removing the artificial pop when striking the strings.

Parallel compression is the solution. a Barber innovation that is more natural than dealing with attack, ratio and release knobs. Barber developed a unique continuous “blend control” circuit, and combined it with a discrete “Class A” FET mixer circuit to allow you to continuously blend the natural signal of your guitar with a “phase-corrected” classic compression circuit. The result? What guitar players have always wanted, unaltered attack with supernatural sustain and resonance. No studio engineering degree required.
