JHS 424 Gain Stage
JHS Pedals · pedal
The JHS 424 Gain Stage is a boutique gain-staging pedal from JHS Pedals designed to function as a studio-quality preamp-style boost and clean gain unit for live and recording use. Optimized for musicians who want transparent gain addition to their signal without imposing heavy tonal coloration, the 424 Gain Stage offers precise volume and gain control suited to stage and studio applications. It complements amplifiers that are already voiced with their own character, adding gain mass and focus without mid-hump staining or aggressive frequency shaping. JHS designed the 424 Gain Stage as a utility tool for session musicians and live players who need a reliable, transparent gain platform. It works well as a foundation layer beneath more characterful drive pedals or as a standalone clean gain source.
