Description
Unleash a symphony of tones with the Dr. Z MAZ 18 Junior Reverb MKII, an 18-watt combo amplifier that harmoniously merges American clean sounds with British overdrive. This amp is a tonal chameleon, perfect for guitarists who demand versatility on stage and in the studio. The MAZ 18 MKII's heart beats with a quartet of 12AX7 preamp tubes and a pair of 6N14N power tubes, ensuring you have a robust palette of sounds at your fingertips.
