The DevTech Audio Precision2 is an analog pedal that combines three functions in one box: distortion, preamp and buffer. RockBoard's PedalPedia describes it as inspired by the Pete Cornish P-2, the British designer's long-running distortion and preamp unit, and says it delivers "extremely a thick, smooth, and harmonically rich distortion tone, ranging from a relatively mellow crunch to searing high gain sustain"1.
What it is based on
The Precision2 takes its circuit from the Pete Cornish P-2, a distortion, preamp and buffer design from Pete Cornish, whose own product page describes the P-2 as one that "delivers extremely fat, smooth, and harmonically rich distortion tones"21. Cornish also offers a Deluxe P-2 version with the same stated distortion character3.
The Precision2 is sold directly by DevTech Audio through the company's own product page, which serves as the maker's documentation for the pedal1.
Controls and bypass
The Precision2 runs with a bypass buffer engaged by default. For players who prefer the pedal out of the signal path entirely when off, RockBoard's PedalPedia states that "the Precision2 features a slide switch inside the unit to turn this bypass buffer off and engage True Bypass mode"1.
The true bypass switch is internal, so changing between buffered and true bypass means opening the unit rather than stepping on a switch.
Components and power
RockBoard's PedalPedia says the Precision2 uses "high quality specially selected and tested components", naming parts from Onsemi, TDK, Panasonic, WIMA and Alpha1. The pedal's technical data lists mains operation for power1.
How it compares
The Precision2 sits among several takes on the Cornish P-2 design. The AMT Electronics Preamp P2 is another P-2-derived unit, listed as a cab sim, preamp, booster, distortion and equalizer4, while Cornish's own P-2 and Deluxe P-2 are the originals the design traces back to23.

Questions
What is the DevTech Audio Precision2 based on?
DevTech Audio describes the Precision2 as inspired by the Pete Cornish P-2, the British designer's distortion, preamp and buffer unit. The P-2 itself is described by its maker as delivering extremely fat, smooth and harmonically rich distortion tones, and independent analysis has described it as smoother and slightly more mid-focused than Cornish's earlier P-1.
Can the Precision2 be set to true bypass?
Yes. The Precision2 normally runs with a bypass buffer, and it has a slide switch inside the unit that turns that buffer off and engages true bypass mode. Players who prefer a fully mechanical signal path when the pedal is off can set it accordingly, while those who want the buffer's drive for long cable runs can leave it engaged.
Is the DevTech Precision2 analog or digital?
The Precision2 is an analog circuit. Its listed technical data gives the circuit type as analog, and it combines distortion, preamp and buffer functions in one unit.
What kind of distortion does the Precision2 make?
DevTech Audio describes the Precision2 as delivering an extremely thick, smooth and harmonically rich distortion tone, ranging from a relatively mellow crunch to searing high gain sustain. That description follows the character long associated with the Pete Cornish P-2 it is based on.
