Do you find a noticeable difference in having the contours on the body being so large, or is it more of an aesthetic thing? Contemplating trying something similar on a project bass I'm working on.
Thank you for bringing this up - it's a favorite topic of mine. On my own designs I personally prefer any contours/bevels to be as deep as possible for both player interface
and for aesthetics. For example, a Jazz bass body is a sensual, sculpted piece of wood - especially the back body bevel. I love the way on the sight-line view of a Jazz bass (while playing) the top edge is not straight. It narrows for the back body bevel and then again for the front elbow bevel, flaring and widening both directions in an organic shape.
My Supernova Mk II pushed the balance of function and aesthetics. The elbow bevel cradles my forearm creating seamless interface while playing. The lowest peak matches the opposite bout so it stands vertical against an amp or wall w/o fear of toppling.
I like tapering a generous back body bevel toward the horn to give a player more shift room depending on their style. On a bass with a standard body bevel, the placement is in a more generic central body position and so if you prefer that specific playing interface, it'll work as designed for those like you. I prefer shifting my basses closer to the neck when playing so first position on the fb is closer to my left hand. Doing this I miss the standard location and the harder edge of the upper horn is hitting my rib. I have a permanent sore-spot on one rib from years of playing my '64 T-bird.
This was a Tele guitar body that I redefined into a bass with radical scallops - one of my first forays into body sculpting. Something about the hard-edged slab body triggered my wanting to make it comfortable. It also brings upon another aspect worth mentioning, which is the functional differences between a bass and guitar. Guitars being smaller and usually lighter with no fear of neck-dive allows a certain flexibility of design. From an ergo focused Strat to a slab Tele and everything in between. A bass brings in a number of functional considerations, some addressed (gen2 P-bass,Jazz bass) and not addressed so much (Ric, T-bird and gen1 P-bass) All cool looking iconic designs no less, but ergo?
On my Supersonic, I took design inspiration from the sculpted Fender Performer, but one step further. Both bevels were exaggerated and the upper horn extended closer to the 12th fret.
I also like imbedding the Strap-Lok peg into the body flush. It brings the strap close to the body instead of the usual 1/2" space it creates with a standard installation. (just don't forget your Strap-Lok equipped strap!) The strap lays against the body better (functionally) and the body looks cleaner (aesthetically).
