to me as price goes up so do the expectations, i wont hold the same requirements and expectations for an introductory amplifier as one that is priced through the fucking moon.
so if i can find a reason not to like a $4,000 amplifier, you had better bet ill be unloading it. that is too much money for me not to like it. people say "its impossible to have perfection in amplifiers, settle for less"
and normally i do. that is why i have a modified 5150, and i dont own a $5,000 amplifier.
or better yet, i build my own gear from scratch.
guitars are the same way - logrithmically the expectations and requirements go up with price.
TBH really this applies to anything i own.
now if im upside down on the gear i wont unload it because i will get more use and value out of it just keeping it. i have this problem right now with a few trades because ibanez steve vai guitars are dead pieces of shit and i found this out the hard way - the only high priced guitar in their line that is still assembly line made. pretty depressing for a guitar that retails $2,400 new.
