Product Description
A set of four tone control knobs for the Quad 22: treble, bass, slope, and filter cutoff frequency. 6mm M3 grubscrews are required, tightened with a 1.5mm Allen key. Do not overtighten. The grubscrew aligns with the D flat on the shaft in each case. The word 'Cancel' has been removed from the frequency knob and a vertical 'off' line substituted for appearance reasons.
