I have found that issue with a lot of my friend's basses. Totally unplayable to me but they kick ass on them. Mostly high action and back bow issues. Old strings too. I offered one guy to adjust his bass for him and when I was done, he couldn't believe how good the bass felt afterwards but.....the action was too low for him and he had me bring the action back up some. I did straighten out his neck though.
