I've got an an audition for a high school honor jazz band tomorrow, and I am awful at EQing. People are constantly telling me "EQ your electric like an upright" but the problem is I don't know how to do that. All I know is that there's not supposed to be a lot of lows, and I also know my 15" speaker won't help that. Also, I've only got the neck pickup on my Fender Jazz to work with, since the bridge died and I haven't had time to get a new one. Help?
