About This Item
Description
Amp Mode is the standalone version of the MOSFET boost circuit inside Jackson Audio's flagship PRISM preamp, distilled to a single silent-turning knob that works as a clean buffer at zero, a subtle push into your amp, or a full preamp-style boost.
Which Jackson Audio boost/compressor is this?
Amp Mode is the exact MOSFET boost circuit found inside the PRISM, released as its own single-knob pedal after repeated requests from PRISM owners. Amp Mode shares its compact 1.8" x 4" enclosure and 9-18V operation with the Blossom compressor, but the two are unrelated circuits: Amp Mode boosts and shapes gain, and Blossom compresses dynamics.
Why guitarists choose the Amp Mode
- The exact same MOSFET boost circuit used in the AMP MODE section of the PRISM, now available as a standalone pedal.
- A redesigned boost knob turns silently, with no crackle, unlike many transistor boost circuits.
- At minimum boost, it works as a unity-gain buffer that protects your tone from signal loss over long cable runs.
- Mechanical true bypass keeps your unaffected tone completely uncolored when the pedal is off.
- A tiny 1.8" x 4" footprint with top-mounted jacks fits on the most crowded pedalboards.
Controls and switches
- BOOST — Sets overall boost amount; fully counter-clockwise, the circuit acts as a unity-gain buffer rather than a boost.
Power and pedalboard compatibility
Runs on a 9-18V DC center-negative supply (do not exceed 18V) drawing a maximum of 10mA, the lowest current draw of the entire Jackson Audio pedal lineup. No battery operation is published for this pedal.

FAQ
What is Amp Mode's relationship to the PRISM? Amp Mode is a standalone version of the MOSFET boost circuit found in the AMP MODE section of the PRISM preamp, released after repeated requests from PRISM owners.
What happens with the BOOST knob turned all the way down? The circuit acts as a unity-gain buffer, strengthening your guitar signal against loss over long cable runs rather than cutting the level.
Does the boost knob crackle when I turn it? No. Amp Mode's boost knob was redesigned to turn silently, with no crackle.
What is the bypass type? A mechanical true bypass switch.
Can Amp Mode run on 18V? Yes, it accepts 9-18V DC center negative; do not exceed 18V.
Is Amp Mode currently in stock? Availability can vary by finish and stock cycle; check the product page for current New vs. B-Stock availability.
