ST, Rosie the Hollowbody is close to 336 size. It is actually modelled after a Yamaha MSG Custom I used to have. I wanted to make something with similar construction to a PRS Hollowbody. The original intention was to have it all Utile with the electrics going in through the pickup cavities so there was no obvious way that it was put together. i.e. I was aiming for a stealth Hollowbody. Unfortunately I made a major cockup when cutting the neck pickup cavity (I had a brain fart and measured the 2mm gap for my pickup rigns from the end of the neck tenon instead of the fingerboard) which meant I had to make a new top and add binding etc to let me re cut the cavity in the correct place.
the PUPs are the Seymour Duncan Hot Rodded Humbucker set. It has a Freeway 6 position toggle switch and a mini toggle to flip between inside and outside coils when in single coil mode. The final switch is a blower switch. No matter where any on the other switches or pots are, flicking the blower switch wires the bridge humbucker straight to the output at full volume. Super useful for selecting single coils with the volume rolled back to get a clean rhythm sound and a flat out HB for solos in a single move.
