1945 Removable Neck Kay M1:















The top and box were opened up, re-arched and rebuilt, new neck and tail blocks. A new custom oversize removable neck with 2 hidden carbon fiber structural beams was scroll grafted to the original Kay pegbox.

Bolt on access is via a neodymium magnetic trap door in the C bout- fantastic for fast neck removal, instant setting of the soundpost, adding internal mics and pickups, and turning complex repairs into easy access simple tasks. You can see that the scroll volutes are missing- common on about 50% of the old Kays we see. Consider it a badge of honor or easy to restore if bothered by it. The original thick Brazilian rosewood fingerboard had a tapered shim added to get the neck angle and bridge height up to a modern 6 1/2″.

Original Brazilian rosewood tailpiece with mint original decal; Upton Revolution Solo pickup.The whole neck breaks down to a tidy small unit that fits in a P bass gig bag and the body easily fits in the seat or trunk of the smallest cars.

This is a fantastic vintage Kay with a ton of mojo and another 50 years of hard gig life in it.

We are always interested in purchasing vintage US made  American Standard, AlCoA and other basses in need of restoration, or models we can use for parts.

Wanted: Original circa 1960-’66 Ampeg Gemini 1,  1966 Fender Deluxe Reverb amps. Gotta beat up old  National Duolian you wanna part with?

1954 American Standard

A beautiful rootbeer color with the perfect patina- not too pretty and not thrashed. This one is on the workbench as we speak for a complete overhaul inside and out. It has that HUGE deep voice that these basses are known for and has undergone a complete neck rebuild including shortening the scale from the giant factory 43 3/8″ to a very fast and comfortable 41 1/2″ for one of the best playing and sounding American Standards you’ll get to play. No scroll breaks or heel repairs, with hidden carbon fiber beams added to reinforce the main neck beam and the heel. These are getting harder to find as the years pass and the demand continues to rise, as they are the benchmark of vintage US plywood basses. Act fast  before we decide to keep it here! $4200.
