The Froggy Bottom Model D12 Guitar is a full sized model based on the traditional 12-fret, slope-shouldered dreadnought body shape. According to Froggy Bottom Guitars their Model D combines the powerful bottom end sound of the traditional dreadnought while retaining clarity and tonal complexity. As with all Froggy Bottom instruments you can choose the body wood from their standard, deluxe and limited ranges - the price you pay will vary accordingly. For example a mahogany back & sides is the cheapest whereas highly figured Koa from their limited range is the most expensive.
