The finest pair of control knobs on Earth for "Tele" style guitars. Machined from lightweight aluminum, then bright nickel plated. Heavy knurling to facilitate volume swells and other tricks of the masters. They match the look and texture of the rest of the Vintique stainless product line perfectly but also look completely at home on an old beat up 'bisquit board'. I measured .774" diameter, .907" tall on a sample knob. Fits industry standard 1/4" solid shaft pots by CTS as found on Telecaster, Esquire, NoCaster, Precision Bass, Jazz Bass etc. Slotted fixing screw. Expertly made by Jay Monterose- the best!
