The "Swiss Army Knife" of Boosts from Jackson Audio
Inspired by decades of legendary boosts-from 60s treble boosters to modern transparent circuits-the Prism synthesizes these approaches into a compact and rugged format. Positioned as the cornerstone of a pedalboard, it unifies your rig and delivers tonal consistency regardless of the guitar. The Violet finish marks a bold look edition without compromising the reliability of the laser-engraved stainless steel enclosure.Who Is It For and What Are Its Uses?
Ideal for the demanding studio guitarist to the stage musician, the Prism Violet shines in pop, funk, blues, rock, worship, or indie. Place it in the first position in the chain to fully benefit from the treble booster and active EQ, either as an "always on" to shape the clean tone or to push a tube amp or stack your overdrives and fuzz pedals with authority and definition.Key Features and Ergonomics
The BODY (bass) and TONE (treble) knobs offer precise +/-15 dB adjustment with no interaction. The Circuit Select switch toggles between COLOR, AMP, and TRANS, while the Pre-Gain offers LOW/MED/HIGH settings to control grit and volume reserve. The BOOST control acts as a master level. The relay footswitch provides access to a programming mode (LED brightness and startup state). At the end of the internal chain, a high-current buffer maintains dynamics even with long cables or crowded boards.Sound
Transparent when needed, colored when desired: TRANS amplifies your tone without compromising it, with JFET character and generous headroom. AMP delivers warmth, musical compression, and harmonics reminiscent of an overdriven amp. COLOR provides the bright attack and cutting midrange of a treble booster, perfect for punchy rhythms and incisive leads à la Brian May, while cleaning up beautifully with guitar volume. The response remains fast, dynamic, and highly touch-sensitive whether playing with a pick or fingers.Technical specifications

Questions frequently asked
What power supply is required for the Jackson Audio Prism Purple Boost?
A 9 V DC center-negative power supply is required, with a recommended minimum capacity of 100 mA. Battery operation is not advised.
Does the COLOR mode function like a treble booster?
The COLOR circuit reproduces the bright attack and sharp mids associated with treble boosters. It suits punchy rhythms and cutting leads, with cleanup possible via the guitar's volume control.
How is the pedal’s EQ adjusted?
The BODY and TONE controls adjust the bass and treble respectively over a range of +/-15 dB. These two active bands operate independently without interaction.
What tones do the TRANS, AMP, and COLOR modes provide?
TRANS amplifies the signal with JFET character and generous headroom. AMP adds warmth, musical compression, and overdriven amp harmonics. COLOR emphasizes bright attack and more piercing mids.
Can it be placed at the beginning of a pedalboard?
The first position in the chain allows use of the treble booster and active EQ. A high-current buffer is placed at the end of the internal chain to preserve dynamics with long cables or a crowded pedalboard.
