If yer patient, I'm gonna be posting some Life Saving devices for both the student and profession studio musician.
Basically gained from years of being not only a studio music but working on the other side of the console and observing the blunders that beginning studio musicians make.

Just off the top of my head....
Step #1: Lock yourself in a room for a weeek and strip your guitar down to its essentials. Find out what strings are the best for you playing style, adjust the action on your guitar to complement your style and abilities, adjust your pickups, adjust the intonation and pickups...clean it... etc etc....
Next on the list, do the same with your other equipment, your pedals, amp, cables and other equipment.
Then check the room you're playing in for ground hums, bad cables, speaker rattles or amps that make rattling noises....


ie, go nuts in a soundproof environment and make your equipment sound as good as it can get......
