The last digit of the serial number appears to be a 9 or a 3. We already have 94139 on this section and 94133 is in our database but without pictures. Both the guitar pictured here and 94133 belonged to Marty Grosz, suggesting that they are one and the same instrument. However, 94133 is described as having a different tailpiece. It is posible that the description is incorrect. The first five digits of the FON are extremely difficult to read (see images below), so that the number quoted above may not be correct. It is possible that two guitars were given the same serial number.

Marty Grosz


One of the few Jazz guitarists who continue to perform with an unamplified acoustic archtop guitar, Marty Grosz (left) augments his fretboard skills with Fats Waller-style vocals and a liberal helping of humour. Marty has appeared with The Classic Jazz Quartet and Orphan Newsboys as well as sharing the stage with other guitarists including Joe Pass, Herb Ellis and Charlie Byrd.
