Beard twitcher here! But I'm able to do so as someone who was lucky enough to see Pantera a couple of times back in the day. There must be plenty of younger fans eager to hear that music live but for me, nah.

What bass are you playing at the moment? Are struggling to play when sitting or standing?
A shorter neck is always going to be easier on the old finger stretches, but it might not be the scale length of your current bass that's causing difficulties.
