Callaham's barrel knobs are patterned after a 50's Broadcaster, and have domed top.
These have a heavy knurl - a direct influence from Danny Gatton. Doing volume and tone swells are far easier than with other knobs, while retaining the vintage look. Drilled for 1/4" solid-shaft pots. Slotted set screws. Nickel plated.
Unlike cheaper knobs these are individually machined from solid brass and then knurled.
