Archtop Guitar Design

The first step is to determine the basic outward design of the guitar.
We've decided, (my client and I), to use a 16 inch wide body - certainly not large as archtops go - we're looking for something with complexity and balance rather than power and projection.
After playing around with my 'standard' archtop design, I've come up with an outline that will be the starting point for this guitar. It's a little smaller than my f-hole model, and I changed the position of the waist in relation to the bouts in a way that I think will compliment the oval hole design.
In this first picture, you can see the initial rough sketch, along with the resulting template and mold.


Materials for the Otis Tomas Archtop Guitar

In terms of aesthetics, we decided that for this guitar, the wood itself was to be the main feature.
The basic design and decorative details were to be kept fairly minimal, but we wanted to find some highly figured and visually interesting wood. After some hunting around the web, we finally settled on a set of highly figured quilted big leaf maple from LMI for the back and sides, and some fine bear claw spruce from Mario DaCosta for the soundboard. For the decorative details on the fingerboard, peghead and fittings, we got some beautiful Arizona ironwood burl from Robert Bradley.
