Froggy Bottom Model F12 Steel String Acoustic 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. 

Froggy Model F12

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.

Uncompromising craftsmanship

I’ve been in heaven this past week, playing my Froggy Model F. What a stunner and what a warm inviting sound! Each string sings beautifully.

Petria’s artwork is more striking than I could’ve imagined. The overall playability is effortless and I’ve already begun writing with it. I’m looking forward to growing old with this instrument. I’ll be playing and composing with it every possible chance I get.

Thank you both again for your uncompromising craftsmanship and incredible customer service.

I am one proud Froggy Bottom owner!
