Lunchbox Hero

“We knew we wanted a low-wattage amp. The challenge was getting a lot of tone and features in a little box. We’re all blown away with how it turned out. It’s going to be great for someone to take it out of the box, set everything to noon, and have it sound great.” – Mark Tremonti

The MT 15 is a commanding two channel amp with balanced aggression and articulation. Now upgraded with JJs 5881 power tubes, the MT 15 punches above its weight class with a large, bold sound, so you can dig in heavy with rhythms but also get singing lead tones out of one amp. Whether recording, practicing, writing, or playing a small room, this amp has everything you need.

The MT 15’s design started with heavier players in mind, but in the end, it has a lot to offer players of all genres. Like the PRS Archon amplifier, the MT 15 features five gain stages before the Master for full, lush distortion. The gain channel gets big, chunky tone with massive, tight low end, but it never loses its articulate note definition or great lead tone. The clean channel is bright and chimey, good with chords and fingerstyle playing – whether with a pic or not. The clean channel also features a push/pull boost control that adds a little overdrive for old school crunch. No matter what tone you dial in, the MT 15 stays balanced across the spectrum with a sweet, smooth tone that won’t bite your head off.

Additional features include an effects loop and bias adjusters that are accessible from the back panel for ease of servicing. Despite its 15 watts, the MT 15 sounds more like 50, so a half power switch that takes the MT to 7 watts is a welcome addition. Bottom line, the amount of features, the hugeness of the sound, and the raw horsepower of the circuit make the MT 15 an impressive lunchbox hero.

The MT 15 is Mark Tremonti’s first signature amplifier.

“A real credit to its namesake and a serious threat to the competition, the MT 15 could well turn out to be PRS’s most popular amp yet…one of the best low-wattage high-amps.”

- Music Radar

“Best in Show / Gotta Stock It Award”

- NAMM 2018, Selected by Sammy Ash

“The outstanding tones of the MT 15’s Clean and Lead channels and their truly independent character would make this amp a bargain at twice its price, but for $649 (USD) it is a best-buy for true aficionados of modern rock guitar tones.”

- Guitar World

"Without a doubt, the PRS MT 15 is the biggest-sounding lunchbox amp I’ve ever played, and I can attest that I’ve played at least 90 percent of the models out there."

- Guitar World

“Between the addictively scorching lead tones and impressively girthy low end, it’s a ton of fun play, and a must-try for any rocker seeking a fierce, compact tube rig in the $1K range.”

- Premier Guitar

“Often, very high gain can easily descend into an unpleasant mush that’s perceived more as noise than music, yet the MT 15 manages to 
avoid this and retains exceptional clarity and articulation.”

- Music Radar

"Simply one of the best hard rock and metal amps out there at this price point."

- Guitar World

"All tone controls were useful throughout their sweep and really allowed sculpting of the sound and EQing for the playing situation and the guitar used. The presence control added a subtle change to the tone that could be used on both channels"
