The Sadowsky Jimmy Bruno Model achieves the goal of a smaller, comfortable guitar that is resistant to feedback but does not compromise on tone.
The smaller body permits a higher feedback threshold and is very comfortable to play. The mahogany neck gives the guitar a rich, warm fullness that makes this instrument sound much "bigger" than one would expect from a smaller body.

From the Henriksen website:
"Jazz guitar amplifiers and jazz bass amplifiers for the discerning, our Jazz Amps are small, light, powerful, inexpensive, warmer than Polytone amps or any other amp including tube amps. A Henriksen jazz amp packs sufficient power to play any jazz club in America. Henriksen Jazz Amps provide the warm sound of tube amplifiers in a light, inexpensive, and reliable package."
I love it. This is the greatest thing since sliced bread.—Jimmy Bruno
