The Dr. Z Maz 18 Jr Reverb 1x12 tube combo guitar amplifier offers 18 watts of sound and one 12" speaker. It features controls for Volume, Treble, Middle, Bass, Reverb, Cut, and Master Volume, with both a high and low input. There's a reason this particular model has become so popular among recording and touring musicians - for the price point, it's tough to find this level of tonal quality, pedal-friendliness and durability. This model is also available in studio format, with a longer square grill.
