About This Item
Description
PRISM packs three completely discrete boost and preamp circuits, a non-interacting +/-15dB active EQ, and a high-current output buffer into one stainless steel enclosure, letting a single pedal cover treble-booster sparkle, tube-amp push, and transparent JFET clarity.
Which Jackson Audio boost/compressor is this?
PRISM is the flagship platform that the standalone Amp Mode boost was extracted from: PRISM's AMP MODE circuit selection is the exact circuit Amp Mode ships as its own pedal. PRISM's MOSFET boost voicing is also shared with the Broken Arrow V2 and Golden Boy boost sections. PRISM also shares its active-EQ approach with Bloom V2, though Bloom V2 pairs that EQ with compression and its own boost/sustainer instead of PRISM's three-voice boost/preamp section.
Why guitarists choose the Prism
- Three completely discrete boost/preamp circuits, COLOR (vintage silicon treble booster), AMP (MOSFET tube-amp-style boost), and TRANS (18V-powered transparent JFET boost), share zero circuitry with each other.
- A non-interacting +/-15dB active EQ (BODY and TONE) shapes tone without one control affecting the other.
- Relay-based true bypass with a soft-touch momentary footswitch is rated for over 100,000 switching cycles.
- A high-current output buffer at the very end of the signal path protects tone over long cable runs.
- Programmable boot-up state and LED brightness let you set PRISM to power up engaged or bypassed, and save that setting.
Controls and switches
- TONE — Active EQ control for high frequencies, +/-15dB, independent of BODY.
- BODY — Active EQ control for low frequencies, +/-15dB, independent of TONE.
- BOOST — Sets the master level of the selected boost/preamp circuit, working with PRE GAIN.
- PRE GAIN switch — Selects HIGH (heavy breakup), MED (mild breakup), or LOW (maximum clean headroom).
- CIRCUIT SELECT switch — Chooses between the COLOR, AMP, and TRANS boost/preamp circuits.
- BYPASS switch — Relay true bypass footswitch; hold 5 seconds to enter programming mode for boot-up state and LED brightness.
Power and pedalboard compatibility
Requires a 9V DC center-negative supply drawing a minimum of 100mA; an internal regulator and charge pump manage voltage internally, so do not power PRISM at 18V. No battery operation is published for this pedal.

FAQ
What is the difference between the COLOR, AMP, and TRANS circuits? COLOR is a vintage silicon treble booster, AMP is a MOSFET boost that emulates an overdriven tube amp (the same circuit used standalone in Amp Mode), and TRANS is an ultra-transparent, 18V-internally-powered JFET boost. Each is a fully discrete circuit.
Can I run PRISM at 18V for more headroom? No. PRISM's internal regulator holds incoming power at a precise 9V, and running at 18V will not change the tone while shortening the regulator's life; an internal charge pump already raises voltage to 18V internally for the TRANS circuit.
Do the BODY and TONE controls interact? No. Both are active EQ controls with +/-15dB of range and are designed to not interact with each other.
What is the bypass type? Relay-based true bypass with a soft-touch momentary footswitch, rated for over 100,000 cycles, plus a high-current output buffer at the end of the signal path.
Can I set PRISM to power up already engaged? Yes. Holding the BYPASS switch for 5 seconds enters a programming mode where you can set and save the boot-up state and LED brightness.
What power does PRISM need? A 9V DC center-negative supply drawing at least 100mA.
