MOSFET Magic That Thinks Like An Amplifier
The Amp Mode uses MOSFET transistors with their unique, impolite characteristics that make it sound like a cranked tube amp. Unlike transparent circuits that give you everything flat like a grand piano, Amp Mode tucks the highs and lows to deliver that perfect mid-boost aggression—the sound of an old tube amp pushed to its sweet spot.

Less Headroom, More Character
Running on 9 volts instead of 18, the Amp Mode deliberately gives you less headroom—and that's exactly what you want. You don't need clinical cleanliness when you're emulating an amp; you want it to break up and do the good stuff quicker. It's designed to add hair to your sound and respond to your guitar's volume knob.
The Circuit That Stacks With Everything.
MOSFET circuits excel at stacking with other pedals and even with themselves. The Amp Mode has that naturally aggressive character that plays well with your entire signal chain, making it the perfect foundation or final push for any rig. It's the kind of boost that makes everything else sound better.
From low setting's unity gain foundation to medium's AC/DC rhythm crunch to high's early Van Halen territory, the Amp Mode covers the full spectrum of tube amp breakup. Each setting picks up where the previous one left off, giving you seamless access to every sweet spot without dead zones.
Your Guitar's Volume Knob Is Part of the Circuit
The beauty of MOSFET design means your guitar's volume control becomes an extension of the pedal. Roll back for cleaner tones, dig in for more gain—it responds like a real tube amp, making your playing dynamics part of the sound itself.
About Brad Jackson
Meet Brad Jackson - commercial pilot by day, tone perfectionist always. His journey from building world-class amplifiers to crafting precision guitar pedals is a story of innovation, resilience, and the relentless pursuit of sonic perfection. For a decade, Jackson Amp Works produced legendary amplifiers that graced stages worldwide, including John Mayer's Battle Studies World Tour. But when the music industry shifted toward digital modeling in 2018, Brad made a bold pivot: he closed the amp company and channeled that expertise into something new. Jackson Audio was born from this transition - not as a retreat, but as evolution. Every pedal carries the DNA of those amplifier years: the understanding of how tubes saturate, how circuits interact, and how musicians actually use their gear. Brad's approach combines the precision of aviation with the artistry of music, creating pedals that solve real problems for working musicians while pushing the boundaries of what's possible in a compact enclosure.
