Gibson TB-3 Mastertone #9550-40
Style 3 was the least
expensive model in Gibson's Mastertone line. It was introduced in 1925 and remained
in production through 1937, when its price was lowered from $100 to $75 and it was renamed
style 75. By
1929, the forty-hole archtop tone ring was standard on the
style 3
tenor, or TB-3, while the PB-3 plectrum and RB-3 five-string were
typically seen
with the twenty-hole flathead ring. This example is a rare original
flathead tenor with an uncut Mastertone label, and is the only known original
flathead from lot #9550. The tenor neck is no longer
with the banjo and it is not known what inlay pattern it had. The wreath
inlay five-string neck is by Ronnie Bales and the resonator was reskinned in the 1980s
by Jimmy Cox.
Style 3 banjos from lot 9550 (see Gibson banjo serial numbers vs. factory order numbers) have been seen with a number of unusual features, indicating that Gibson may have used this lot as an opportunity to clear out some leftover parts. #9550-13 is equipped with a mute-style armrest but no internal mute mechanics are present; #9550-33 lacks a Mastertone block; #9550-36 features an unusual inlay combination; and #9550-47 has full wreath inlays.
