Froggy Bottom F12 Guitar

The Froggy Bottom F12 Model – a full-sized 16” guitar with 4.125” depth (significantly shallower than dreadnoughts) – was inspired by the instrument resulting from the chance conversion of a broken Martin F-7 arch top back in Greenwich Village of the 1960s.

In 1965, someone brought a old Martin F-7 with a trashed top into Marc Silber’s shop in the Village, wondering if it could be salvaged. Marc replaced the original arch top with a flat top and what had been a rather pedestrian guitar got a lot more interesting. As the guitar made the rounds in the Village scene, it caught the attention of players and builders alike. People started bringing the old F-7s into Matt Umanov’s shop for conversion. Word got around.

These early conversions demonstrated the sonic virtues of reducing the volume of air in the bodies of larger instruments and altered the course of contemporary flat top guitar design.

The shallower depth of the Froggy Bottom F makes the instrument comfortable to play and contributes to the guitar’s exceptional string-to-string balance, clarity, and projection.

In every regard, I am extremely happy with the F 12 and it is the finest guitar I have played. I can drive it like a Dreadnought and fingerpick delicately like James Taylor. Okay, maybe not exactly like James Taylor, but he doesn't know he is missing! There is nothing that I dislike. Alternate tunings are simply grand. It is supremely inventive, and as you know, that is my highest honor to bestow upon a guitar. It is quite special to play a guitar with perfect clarity and intonation and beautiful nuances, fully new to my ears. As you noted, it might be a bit "jangly" for a a bit of time, but let's have some respect for Roger McGuinn until she settles in! Turn, turn, turn. :)
