Funny that you would mention feeling at home. I love Ricks, but J's are thin in weird places, and the string spacing at the bridge feels like crossing a canyon to me, not to mention that the shape of the body feels wrong. Personal experience is a strange thing.
Exactly, it is, and it's great we have so many different models, shapes, sounds and options to choose from! Personally, I'm still trying to be comfortable with the Rick, but that difference in shape and ergonomics makes me approach the instrument and the bass lines in a totally different angle, and for me, it helps me to become a better musician.
