Two Questions: 1) What actually happens to a bass/guitar when it gets old? By old, I mean 10 years or more. 2) Do you think the average bass sounds better as it gets older, worse or is there no difference? My Ibanez Musician is 23 yrs old, and I bought it brand new, but, I honestly can't tell if it sounds any better than the day I bought it. It still sounds great, but, I can't tell if there's been any change in its sound. What do you think? Mike J.
