THE FOLLOWING DETAILS AND DESCRIPTION ARE TAKEN FROM THE PETE CORNISH WEBSITE:
The PETE CORNISH P-2™ is highly recommended for a fat, high-gain, searing lead sound and is perfect for solos and heavy rock rhythm work. This pedal is used prominently by David Gilmour of Pink Floyd and Paul McCartney. The P-2™’s full, bright sound cuts through the mix effortlessly and was the recipient of the Editor's Pick Award from Guitar Player Magazine, receiving the following review:
"The PETE CORNISH P-2™ delivers extremely fat, smooth, and harmonically rich distortion tones, ranging from a relatively mellow crunch to searing high-gain sustain. The pedal is also extraordinarily responsive to playing dynamics, cleans up nicely with even slight guitar volume adjustments, and it provides nearly uncanny single-note definition within chords. Finally, it can crank out insane amounts of gain. Astonishing! Extremely fat tone, quiet, great dynamics, infinite sustain, exceptional chord definition".
The input to this unique device is our universally acclaimed High Impedance, Unity Gain, Class A, Buffer Preamp with it's superior RFI rejecting capability (to eliminate Radio Station interference) and Low Impedance Audio output, allowing the use of extended cable runs from the P-2™ in bypass mode. The fixed High Impedance load presented to the Guitar allows the pickups to operate at their optimum, even when several effects units are connected after the P-2™. The Unity Gain Buffer also prevents "Ghost Distortion" being audible in Bypass Mode. This effect unit gets the most benefit from being fed into a clean, full frequency response amplifier and I recommend that when you receive your pedal you connect it up without anything else in line, just Guitar/Pedal/Amp, and discover the way the controls interact, both with themselves and the guitar/amp controls. Then adding the rest of your effects, you may find that you need to make slight adjustments to these to compliment the constant signal level provided by the P-2™.
The tone facility on the P-2™ has been designed to provide an attenuation of 14dB at 3KHz when set fully Counter Clockwise. When the tone control is set fully Clockwise it provides the maximum Harmonic Content to the signal. Settings in-between CW and CCW will provide varying amounts of high frequency attenuation: experiment to find your optimum setting. The tone control features fully passive frequency attenuating components that do not cause unnecessary phase shift or uncontrolled mid range problems.
