Hi guys! I got a bunch of craft foam in the post today, so I thought do a straightforward ergonomics study with the current version of this design. I will hack into it and update it, incrementally improving it over time. It's a multiscale 7 string, 680mm (26-3/4") on the bass side and 648mm (25-1/2") on the treble side, with 24 frets. The access up the neck is such that I could put some more frets between the pickups, and it would be perfectly playable, but then it's nice to dig in under the strings so I probably won't! Might be good for tappers / shredders / technical players with a really light touch though, and I do want to try it. Obviously it doesn't have strings, but I did model the string plane and marked it to get an idea of where the frets will be. First impressions are pretty good! I still need to do the neck profile, for now it's 2" thick like the body so it neck dives a bit, and I need to sculpt contours in the back to inform the 3D model. Many more iterations to come! The posture and playing position is really nice. It sits just inside the playing arm a bit like an acoustic, so even with the neck dive it's easy to point it where you want it. It works great playing in standard position, and I can see it being very easy to shred up the neck in classical position. Anyway here it is! Let me know what you think as always, I'm looking for ideas as to woods / finishes / construction, basically everything! Cheers!
