The Moskyaudio G III BLUE is a compact distortion, overdrive and preamp pedal that Moskyaudio describes as based on the REVV G3, the pedal take on the purple channel of REVV's Generator 120 amplifier. It carries a three-band EQ and four adjustable aggression settings for gain shaping, and Moskyaudio lists it for both guitar and bass.1
What it does
Moskyaudio positions the G III BLUE as a Purple Channel preamp, overdrive and distortion in one box. The maker's description says the G3 design is "inspired by the renowned Generator 120 Purple Channel, boasts one of the most distinct tones found in contemporary amplifiers. It offers exceptional clarity and tightness, coupled with just the correct level of saturation to suit any musical scenario."1
The original it draws on is well documented. The REVV G3 is a solid-state, mains-powered distortion pedal, according to Guitar.com's review,2 and Pedal of the Day called the G3 Overdrive Distortion "a true amp-in-a-box effect."3 Delicious Audio describes it as the pedal version of the purple channel.234 In a demo video, guitarist Pete Thorn said: "this pedal models the Distortion sound of a REV amplifier I do believe and share some of the characteristics uh with the" actual distortion channel of the amp.5
Controls and features
- Aggression: 4 adjustable settings for customized gain levels1
- EQ: 3-band EQ with controls for Bass, Middle, and Treble shaping1
The aggression switch is the feature carried over from the REVV G3 concept that gives the most range: four gain-structure choices rather than a single voicing, so the pedal can be set from lower-gain overdrive through to saturated distortion. The three-band EQ then shapes the result, with dedicated Bass, Middle and Treble controls.1
Power and practical details
The G III BLUE runs on a 9V DC supply with negative tips, and Moskyaudio recommends a regulated supply.1 The pedal measures 11.5 x 6.5 x 5 cm and weighs 320g, so it sits in the compact range of pedal sizes.1 True bypass switching keeps the circuit out of the signal path when the effect is off.1
Moskyaudio also makes a companion model in the series, the Moskyaudio G IV RED, for players comparing the two channels. For more on the effect type, see Distortion Pedals, Overdrive Pedals and Preamp Pedals1.
