Prs Guitars Mt15 Mt15 Tremonti HeadThe MT 15 is a commanding two channel amp with balanced aggression and articulation. Powered by 6L6tubes, the MT 15 has a large, bold sound, so you can dig in heavy with rhythms but also get singinglead tones out of one amp. Whether recording, practicing, writing, or playing a small room, this amp has everything you need. The MT15s 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. Theclean 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 andbias 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 thecircuit make the MT 15 an impressive lunchbox hero.
