Yes Honey, you're really good at those trade offs. I told you that you have a genius ear. Mookie was going easy on you though but you could always move to the front of the stage and do a solo, while he can't go anywhere. Oh you'll catch up to him, just keep at it. I couldn't do such challenges myself, I'm out of practice. Too much songwriting. And that chick singer I have to work with consumes souls. Your guitar giving feedback is its way of saying "You're losing!" Feedback is a musical instrument, however. Didn't you know that? It's like an extra tool your electric guitar carries with it. You can get feedback at low volumes by playing with all that gain you have, and that way you can practice in your bedroom various muting, volume, tremolo and position techniques. Few people can master this. Most of them just stand in front of the speaker, wave the guitar around and think themselves artists.
I used to do sound occasionally to help out some friends. That's what a sound guy usually is: a musician who doesn't deserve to perform. I guess "deserve" is a harsh word, but someone has to do sound. And this someone has absolute control of how the crowd perceives your music. It is wise to have a sound guy as another member of your band, just remember that it's not that simple. PA stuff is expensive and heavy, and you can get into quarrels with venue, organizers and local government. Rock and Roll!
