SWART ASX MKII is a Headrush tone pack based on the beautifully expressive Swart AST Master MKII—a modern boutique classic inspired by small, hand-wired American amps of the late ’50s and early ’60s. Known for its rich harmonic bloom, soft compression, and organic breakup, this amp is all about feel, nuance, and musical response.
