The MG15R has the same features as the MG15 but with an added Reverb control to give you that big stadium-like sustain! Compact 15W amps that pack plenty of power. The 8” speaker delivers a great sound for practice but can also hold its own in front of a small crowd. These amps bring an added punch and lower-end to your sound. The variety of tonal options are sure to compliment any style.
