Paul Reed Smith Mark Tremonti MT15 Amp Head Unleash your inner headbanger and plug into the high-gain Paul Reed Smith MT-15. Designed in collaboration with Mark Tremonti, the MT-15 offers huge amp sound in a small package. Powered by a pair of JJ 5881 tubes, this amp cranks out 15 watts of crunchy tone. Practicing at home? Just flip the amp down to 7 watts and hit that sweet spot without all the volume. When you kick on the dirty channel, the MT-15 switches from a blue backlight to a menacing red. And with five gain stages, this amp has more than enough sizzle on tap for any players of any style. The PRS MT 15 is a commanding two-channel amp with balanced aggression and articulation. Powered by JJ 5881 tubes, the MT 15 has 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.
