Kent, Ohio - Photos and a Brief Historical Description





Click the image below and watch a video of the Thurman Soundport guitar in action!

Click the above Photo to see an mpeg video of Blues and Ragtime expert Andy Cohen playing a Thurman Soundport guitar (29 mb download). This is the sample instrument from China. The first models are here in a natural finish and now red sunburst, including a nice case. My name is inlaid on the head and there is an internal label with the patent number. This is the greatest sounding guitar you can imagine. Call for pricing and deals.

About Thurman Multi-dimensional Sound Ports

Along with my constant repair and sales work I occasionally build a guitar. Over the years I have developed a design principle which improves the tone and projection of the instrument. The generic name is the "Three Dimensional (3-D) Sound Hole." I also call it the "Thurman Multi-Dimensional Sound Port."

Actually, they come in pairs and are located on either side of the neck and extend out to the curve of the upper bout. They are "multi-dimensional" because each continuous port simultaneously exists in both the front and side panels of the guitar. These new symmetrical, bilateral sound ports allow the acoustical energy trapped in the upper bout to flow efficiently out and forward. The player's hand, reaching up the fingerboard for notes over the body, doesn't touch the edge of the instrument because that area is now open!

This design principle is protected by a patent (U.S. and Canada) and is reserved only for authorized manufacturers. I believe it is a major enhancement to the sound and playability of the purely acoustical instrument: be it steel string or classical, guitar or violin.

Have a look at this:

Harmony combo amp/guitar/microphone and stand.  This outfit would put you into the music business in the late 1930's or just after World War II.  The items match in design, especially the color scheme of the guitar case and amp cabinet covering.  The microphone is a dark red bakelite with an early form of the piezo diaphragm system called "Rochelle Salts." This outfit is not for sale (in for repair) but is shown for your interest and ooohs and aaahs.  Photo: Harmony Outfit
