Originating from the Green Beret and Invader 50 lineage, the Invader 65HV celebrates our tonal heritage with remarkable proficiency. While retaining the authentic rock and roll character that established its predecessors, we’ve expanded on its capabilities with more power handling and a vented 50 oz. magnet giving greater SPL and thermal relief.

These build attributes result in a wide-ranging, potent voicing suitable for whatever style of guitar inspires you. Expect a refined harmonic profile—offering midrange complexity, smooth top end shimmer and a formidable bass presence. This design maintains extraordinary sensitivity to playing dynamics responding with remarkable clarity to every nuance of your technique, whether delivering delicate passages or commanding rhythmic chunk.
