Description
The PRS Mark Tremonti Signature MT 15 is an amplifier head that delivers a powerhouse of tonal versatility in a compact form. This amp is crafted for guitarists who crave high-gain intensity and crystalline cleans. Conceived in collaboration with Mark Tremonti of Alter Bridge, the MT15 is designed to handle both the stage and the studio, offering a range of tones that cater to rock, metal, blues, and beyond.
At the heart of the MT15 is its two-channel design, featuring a high-gain lead channel known for its saturated distortion and a clean channel that sparkles with clarity. Each channel is equipped with its own set of controls, allowing for precise tonal shaping. For those quieter practice sessions or intimate gigs, the MT15 can be dialed down from 15 watts to 7 watts, without losing the amp's rich tonal character.
The MT15 doesn't just excel in sound but also in functionality. It includes an effects loop for integrating your favorite pedals and external bias controls for easy tube adjustments. A single-button footswitch is part of the package, making channel switching seamless during performances.

PRS MT15
These sound great for rhythm but, also have an extremely tight lead sound. Single notes are very focused sounding which I haven't found in many amps. The low end is lacking a bit compared to big amps but, when recording you low cut guitars tracks anyway so it's not as big of a deal in these situations. I add a Tube Screamer TS-808 and find it sounds awesome this way.
