Description

Unleashing a blend of vintage character and modern versatility, the Dr. Z MAZ 18 Junior Reverb MKII is a compact powerhouse designed for guitarists seeking tonal excellence both on stage and in the studio. This 18-watt combo amplifier merges the classic warmth of American cleans with the distinctive punch of British overdrive, delivering a dynamic range that caters to various musical styles.

At its core, the MAZ 18 MKII is driven by a quartet of 12AX7 preamp tubes and a pair of robust 6N14N power tubes, promising rich, full-bodied sound. The inclusion of a master volume placed after the phase inverter allows for maximum tube saturation at any volume, ensuring your tone retains its integrity whether you're practicing at home or performing live. The spring reverb adds a lush, ambient quality, enhancing your soundscapes with ease.

For those who love to integrate effects, the buffered effects loop ensures seamless pedalboard integration, maintaining clarity and definition in your signal chain. The amp's EQ-bypass footswitch provides a boost when you need it, pushing your tone over the top for solos or climactic moments in your set.

The MAZ 18 Junior Reverb MKII is not just about power; it's about precision and adaptability, making it a reliable companion for musicians who demand both quality and flexibility.
