I used 9's once... then moved to 12's... wow... don't do that! I was still a beginner, so I really didn't know what I was doing when I got 12's... but they do sound better! I then moved to 10's... although, I have an 11 for my high e on my ibanez right now cause my local shop was out of single GHS .010 strings, so I got an 11 instead, since I had only broken my high e, the other 5 were still pretty new.
I'd say give the 10's a try, if you don't like it, then you're out like $7... though, I'd give schmange's advice a try first and try messing with the EQ and the tone and volume knobs and pickup selection on your guitar first. cause that won't cost you a nickle! (well... ok... maybe you'll spend a nickle in the ammount of electricity it'll take to power the amp... but other then that you won't spend anything! :cool: )
