Six '50s style cocoa brown phenolic plastic amp knobs. Styled like '50s DAKA-WARE knobs. Slotted set screw fixing to standard 1/4" USA solid shaft pots. Also fits imported pots with 6mm solid shaft. I measured 1.193" overall length. Great for custom building or fixing up vintage amps. Set of 6. The color of this knob is similar to the reddish brown knob we sell but lighter.
