This TB-1 conversion is from a batch of 50 banjos made from leftover late 20s TB-3 parts. According to it was built between 1937 and 1941. 

It was previously played and owned by John Ramsey, who also owns Tejon Street Music. Here's what he has to say about it:

This is a great, lightweight banjo that plays well and sounds wonderful.  It's a really unique instrument, and I wouldn't be selling but I found another banjo from the same batch with the original finish on the resonator.

Includes brand new CH-020-J Guardian hardshell case.


  • Maple neck and maple resonator
  • 2-piece flange
  • Full 3/4" shell
  • One coordinator rod with long adjusting nut
  • Original 2-piece-style late 1920s arm rest
  • Tension hoop is pre-war tenor with chrome plating
  • 1/4" round tone hoop
  • 3-lug shell and resonator. Originally had 4 lugs and L-brackets but holes were filled and finished over at the factory

Neck Notes

The neck was built by an unknown maker, but it's nice quality and very playable.

There's a round plug in the back of the neck between the handstop and the first fret. It was finished over when the neck was built. The only explanation we can think of is that when the neck was made, the truss rod pocket was perhaps cut too deep and a repair was done to the back of the neck. It is structurally and cosmetically solid and does not affect the feel or playability of the neck.


All hardware is original except for the tailpiece and tuners. Tailpiece is modern Presto reproduction and tuners are circa 1950s Eltons with a modern 5th string peg.

Old refinish to back of resonator with some splits and cracking to outer veneer layer. The cracks have been glued and are solid.

Frets in very good condition.
