I'm a relative novice player of 2 years now. I've been trying to get a better understanding of you veteran players' terminology when describing tone. My amp (Fender Champion 20) offers some limited effects which I can clearly hear and describe. The terms "tight, headroom, saturated tubes, overdriven, bite, crunch, scooped mids, high gain, etc" leave me puzzled by what you mean though; just not enough experience yet I guess. These terms are not effects, but instead amp or pickup tone characteristics.....correct? This amp offers 12 "voicings" I toy with and have zero'ed in on Blackface and British settings as my favorites. I turn the effects completely off and just listen to the tonal differences. Do you guys get classic rock tones with cleaner amp settings........or is that an oxymoron? I've read that guitarists like Angus Young actually play with cleaner settings, plus lots of volume obviously..........is this true?
