1920s Concertone (Regal) 4-String Banjo-Mandolin Conversion

Overview: This is a simple, no-frills, easy-to-enjoy banjo-mandolin that I've converted down to a 4-string format for ease-of-use and ease-on-the-ears. This makes it, effectively, a "mini tenor banjo" in operation and it's well-suited to chord-chucking and melody, both. While it has a "Concertone" brand on the dowel, this is almost certainly made by Regal in Chicago.


It has a good, even, clean sound to it. The neck is a little on the bigger side front to back but is still quite comfortable.


Repairs included: I leveled and dressed the frets, reglued the dowel (as I recall), fit a new synthetic head, added side dots, converted it to a 4-string format, fit a new bridge, cleaned it up, and set it up. It's playing spot-on and ready to go.

Condition notes: The head, tuners (nice new Gotoh ones), and bridge are replacements. It's otherwise original. I've added a bolt behind the neck brace that does the actual job of securing the neck to the rim in a rugged fashion. The neck brace remains just to dress it up.


It comes with: Sorry, no case.
