The Hammertone Chorus is a single-effect modulation pedal designed in-house by Fender. It produces chorus sweeps described as glassy and shimmering, with three selectable chorus types for classic chorus voicings and a separate tone switch that lets the effect sit further back in the mix.

The enclosure is aluminium with metal hardware, finished in gray with teal accents and fitted with custom-colour knobs carrying the Fender F logo. Footswitching is true bypass, so the signal path is left untouched when the effect is off. Input and output jacks are mounted on the top edge, which saves board space and gives more routing options when several pedals are stacked together.

The pedal runs from a 9-volt centre-negative power adaptor, which is not included, and draws 100 mA. Input impedance is 500k ohm and output impedance is 470 ohm. A Fender parts and accessories 2-year limited warranty document and owner's manuals in many languages are listed as downloads.
