This is essentially the Allan Holdsworth guitar. Toms student has bought a few of them custom ordered from the builder. I usually don't get very excited about a guitar like this but I sat and played it for a few minutes through an amp and not only is it incredibly easy to play (22" radius ) but it is the most acoustically balanced instrument I've ever had in my hands. Every note rings perfectly at the same level as any other note on the instrument. I played some fairly dense Holdsworth-style chords and they sounded incredible. The intonation is crazily spot on for such close intervals. The body is completely hollow with no center block. Its a small instrument but still a 25.5" scale length. It also has 25 frets (request from the customer, not a standard feature). I really loved playing the instrument although if I saw it first in a store I wouldn't have picked it up to play in the first place.
