I have a guitar that just today I completely removed its relief while strung up in order to evaluate it for leveling. Because of some schedule things I left the old strings on, fixed its action, pickup height and intonation and decided to just play it and deal with it later. I like this guitar a lot, how it looks and sounds and feels, but now it's like this guitar just WOKE UP. Seriously! It's a Gibson ES-339 with PAF humbuckers. It seems way more crisp and tight and resonant than it used to be, no mud or boominess in the neck position which I thought was a problem before. Have I done a bad thing, and can I keep it this way?
