But yeah @engedi1, I'm with ya.
I can't get comfortable on a non contoured bass.
Recently a music store near me had a Fender Aerodyne Jazz in stock.
They didn't realize it was a Japanese model and had not priced it... let's say, accordingly.
Super cheap.
I thought I had always wanted one, and I did, for years.
I wanted one while driving to the store.
I wanted one when I entered the store.
I wanted one when I saw it, I wanted this one.
But then, I played it, grabbed a strap plugged into an amp...
No hip contour, no arm contour, all uncomfortable.
I no longer wanted it, and left very sad.
