My resophonic guitars are built much like the 30’s wooden reso guitars that we're all familiar with, though I’ve made a few important improvements.
Yanuziello Resophonics all have an ultra light soundwell under the cone. I’ve designed it to enhance the air flow within the body chamber. The holes in the soundwell are quite large in diameter leaving a strong, lightweight bridge-like frame structure to hold up to the reso string tension.
Much like a banjo, the neck has an integral pole which extends into the soundwell area, creating a very strong, mechanical neck to body joint.
I build the bodies of my reso guitars deeper, which I feel enhances the whole tone spectrum, not just the bottom end.
I build both square and roundneck resophonic guitars with a cutaway option on the roundneck model. “f” holes are optional on either model.
