The V2 sag knob may differ, lacking the semi-octave effect found in the V1, potentially altering its utility for achieving specific tones.

The Sag knob adjusts the pedal's power supply, mimicking a partially drained 9V battery, creating a 'brown' sound similar to an amp on the edge of breakup.

Fully clockwise Sag delivers the full 9 volts, acting as a clean boost with low drive; lower Sag settings emulate a small combo amp's low-end breakup.

Described as changing bias voltage on JFETs and transistors, the Sag knob influences the pedal's clipping symmetry, affecting distortion character.

The Barbershop OD provides sweet, transparent low-gain overdrive, comparable to an OCD but with less gain and a 3-position tonal switch, unlike the brighter BD-2.

The EAE Halberd is highly recommended for stacking, providing a complementary tone to the Barbershop.

A Colorsound Overdriver style pedal, like the Blammo Voltage Driver, stacks well with the Barbershop for enhanced tonal depth.

Some users feel the Barbershop has a distinctive "murky" tone, contrary to the "transparent" description, offering a unique Fairfield sound quality.

When used with a Strat and Lace Sensor Gold pickups, it works well as a boost, transforming an anemic signal into a lively, edgy tone.

Stacking two Barbershops in series can achieve unique fuzz tones, as demonstrated in Andy Shauf's "The Magician" with varied Sag settings.

The Barbershop excels in delivering transparent breakup and saturation, particularly with amps that have desirable inherent characteristics.

Owners report that the pedal adds low mids without the typical compression, enhancing dynamics and making play more exciting and responsive.

Players find the Barbershop highly responsive to pick attack and input stacking, allowing dynamic changes from clean boost to overdrive with volume pedal manipulation.

A boost pedal, like the EQD Arrows or MXR Mini Booster, effectively enhances the Barbershop's gain, adding saturation and grit.

Using an EQ pedal with gain, such as the Boss GE7, after the Barbershop adds tonal flexibility and can integrate compression for a varied overdrive effect.
