From Fender:
"The Dick Dale Stratocaster® guitar honors the sound and style of the self-proclaimed King of Surf Guitar, with features including an alder body, specially shaped maple neck with reverse headstock, rosewood fingerboard, three Custom ’50s pickups with special switching, master volume control and original synchronized tremolo."
While mostly original, the only modifications done to this guitar are the added stacked humbucker in the bridge position and the bypass switch was moved from above the selector switch to in between the selector switch and the volume knob. It has the OHSC with no COA.
