So I was thinking of either building or having somebody build me a modern Mando-bass. Mine would, however, differe significantly from the historical mandobass: It would be mandolin/bass guitar shaped. Probably either Acoustic/Electric hollow, or Semi hollow. I'd like to try to get it to be F-style mandolin shaped. If it was semi-hollow or hollow, I'd probably put normal bass pickups in it. Could this work? I would also like it to be double-coursed. I was thinking either EeAaDdGg tuning, or maybe EE AA DD GG, or a mixture, but I'm not sure which would be most practical. For the bridge, I'd probably do something Gibson guitar-style. Could this be done? Would it be a money trap? Would it be playable or practical?
