Okay, while I'm researching which higher end amp to buy, I'm using a guitar amp to practice on. My question: What should I set the settings for? Below are the settings available: Volume: Gain: Master: Treble: Middle: Bass: What do you recommend for maximum enjoyment, without blowing out the amp? Oh yea, buy the way, it's a Squier 15 guitar amp (yes I know, very, very poor quality already). Thanks!
