No one stated that you had to LIVE with a less-than optimal sound.
That can be changed easily. Turn a knob. An uncomfortable neck? You're stuck with it.
Exactly. I can get a few good sounds out of basically any bass I've come across, even just using my hands and the bass's controls. Add in amp controls and I can change the sound in all kinds of different ways. Then there are all the ways I can change pickups and other electronics to change the sound.
An uncomfortable neck will be an uncomfortable neck no matter what I do, short of fairly extreme modification.
