Need more power? The Green Matamp  GT150 is a dual purpose high power head for guitar and bass. Designed for ultimate clean headroom but with enough gain to satisfy most, the GT150 is not for the faint hearted.

For bass duties the GT150 delivers a gritty midrange drive that really cuts through while guitarists get levels of dynamic punch that have to be felt to be believed.

Now featuring the excellent Gold Lion KT88 valves as standard the GT150 delivers over 150w of clean power to either 4 or 8 ohm loads (we recommend a 400w cab minimum). At 10% THD the amp delivers 200w and keeps going well beyond when driven.

The preamp takes elements of the GTL design but has been tweaked for more low end punch. Capable of delivering both clean and crunch sounds with classic Matamp tone.

Huge transformers, massive filter capacitors and hand wired turret track construction will give years of reliable service.

Available as standard black or custom Green (as pictured), this amp is set to dominate your live sound.
