The battery thing isn't a big deal, especially if these aren't gigging instruments. Strings break, pots get dirty, cables need replacing, tubes go out. I don't know why battery replacement is such a deal breaker for many.
I've personally never understood why so many players FREAK OUT over the concept of batteries. They are terrified that the battery is going to die, when the chance of that happening is no more concerning than any other thing that could go wrong. And then they make excuses that batteries are a big hassle and cost too much. The reality is, you pop a battery in and forget about it, then replace it once a year or so to be safe.
Some people will go as far as to wire up an elaborate external power supply so that their 85uA opamps won't have to deplete batteries. Isn't that far more likely to fail? What if you forget to take the power supply with you, or don't have any spare TRS-TRS instrument cables?
