These bell-shaped control knobs are designed to provide a precise, reliable fit on a wide range of Gibson, Epiphone, and imported electric guitars. Made from durable moulded plastic with clear numbering, they offer smooth rotation and an authentic vintage-style appearance commonly found on Les Paul, SG, ES, and similar models. Available in both imperial and metric versions: Imperial (US-spec) – suitable for Gibson guitars using coarse-splined 24-tooth potentiometers. Metric (import-spec) – suitable for Epiphone and most Far-East-built instruments using fine-splined 18-tooth potentiometers. These knobs use a simple push-fit design with no tools required, making installation quick and straightforward.
