I've been playing for over a year, and I can tell some difference (for example my Gibson LP studio compared to my strat knock off), but like between amps it's very hard. For example, yesterday I tried a Peavey Valveking 112, and i could tell a little difference, but nothing major (and my amp isn't that good so there should have been a major difference).

So my question is, how do I devolope an ear for tone? Just try a bunch of amps?

Listen to more music. Play around with your amp settings and get to know what boosted mids/lows/highs sound like

I listen to a ton of music.

Yeah, that's a good idea, but see with my amp the bass is very high, so i always have to keep it on 0 and treble close to 10.
