"If you're playing rock guitar, there's a real temptation to use way too much distortion to get what you think is the sound on records. Most great rock guitar tones are much cleaner than they sound. When in doubt, use less gain."
So true it hurts. I'm a guitarist of three decades and I worked as a recording engineer through college and occasionally as a hobby since then (I went to school for audio engineering). The number of times I've had to beg, plead, cajole, and threaten a guitarist to cut the distortion is huge.
The hallmark of an amateur guitarist is mosquito tone. There's a belief that it masks errors, and it does, but it's such a glaring error in and of itself that it's not worth the trade-off.
