Jackson Audio Prism Overdrive, Boost, Preamp, EQ, Buffer Pedal – Silver Jackson Audio

PRISM – Buffer, Boost, Preamp, EQ and Overdrive, Silver

Designed as the ultimate tone shaping tool for a player’s pedalboard, the PRISM is a buffer, boost, preamp, EQ and overdrive all in one beautiful and compact stainless steel enclosure!

Much like an optical prism, which takes white light and breaks it apart into the different colors, the Jackson Audio PRISM takes your guitar’s natural tone and allows you to boost it, shape it and transform it into a new tone that is uniquely you!

Use it shape your tone, slam the front of your amp or add new dimension to your existing pedals, any way you use it, we believe the PRISM will be the cornerstone of your rig for many years to come!

PRISM OVERVIEW

The PRISM was designed using a systems approach to tone shaping. While the PRISM contains many features and circuits, those circuits are precisely crafted to work in harmony with each other to create a unique tone shaping tool with unrivaled flexibility and performance!

EQ/TONE SCULPTING

The PRISM was conceived between Brad and Nigel as a tool that players could use to unify their rigs regardless of the guitar being used. Since many guitarists will swap guitars but keep the same pedalboard and amp, we wanted to create a tool that would allow the players to re-voice their rigs for the guitar chosen and the +/-15dB active EQ in the PRISM accomplishes this with ease.

BOOST/PREAMP

As a boost/preamp the PRISM contains three of the most distinct voices of boosts available. A transparent clean boost with no tonal coloring (TRANS), a boost that emulates a vacuum tube amp (AMP) and finally the boost circuit that started it all, the silicon treble booster (COLOR). These three circuits represent over 50 years of guitar effects from the earliest guitar pedal ever made to the more modern transparent voiced circuits.

BUFFER

The PRISM is a true bypass pedal featuring our own silent switching circuitry and uses relays with a soft touch momentary contact footswitch to accomplish the bypass. We chose relay bypass because it is far more reliable than traditional mechanical true bypass methodologies and the relays themselves boast a lifespan of over 100,000 cycles!

At the very end of the PRISM we included a high current buffer that is used to strengthen your signal and preserve your tone regardless of how complex your pedalboard is or how long the cable run is back to your amp.

TONE CONTROL

An extremely powerful active EQ, the TONE control adjusts the high frequencies by giving a +/-15dB boost/cut to those frequencies.

PRE GAIN SWITCH

Selects between 3 varying levels of gain for each boost circuit.

• HIGH – Voiced for heavy breakup/lead tones.
• MED – Voiced for mild breakup/rhythm tones.
• LOW – Voiced for maximum clean headroom.

BYPASS SWITCH

The BYPASS SWITCH is used to turn the PRISM ON/OFF and is also used to enter programming mode.

BODY CONTROL

An extremely powerful active EQ, the BODY control adjusts the low frequencies by giving a +/-15dB boost/cut to those frequencies.

BOOST CONTROL

The BOOST control sets the overall level of boost available from the PRISM. Think of the BOOST control as a master volume that works in tandem with the PRE GAIN switch to dial in the ratio of gain to boost level.

CIRCUIT SELECT

Selects between the 3 boosts circuits available in the PRISM.

• COLOR – Vintage Silicon Treble Booster Style boost. Perfect for Brian May (Queen) style rhythm and lead tones!
• AMP – A very musical sounding MOSFET boost that emulates the tonal response of an overdriven vacuum tube amp!
• TRANS – An ultra transparent 18V powered JFET boost circuit. Sounds like you only LOUDER!

INDICATOR LIGHT

The INDICATOR LIGHT indicates the ON/OFF status of the PRISM and changes colors to give a visual indication of the level of boost selected.
