Hey there. So I'll make this brief. I'm a high school student who plays the Double bass, and I have experience playing bass guitar, but haven't owned one. Well for my design and engineering class, I'm taking on a building challenge to build a hybrid instrument. The concept is simple, to make an instrument which is a solid body bass guitar in every aspect, except for the addition of a curved bridge, much like the on on a double bass, and a curved fingerboard to go along with it. The bridge wouldn't be as high as a DB, the highest I would care to build it would be 3" above the body. I just wanted to know if anyone else has attempted something like this, or if such a thing already exists. Any feedback and info is appreciated.
