My amp is tubed so I wouldnt need a tube screamer.

Not true...my amp is tube also. The dirt box just overdrives the amp and gives it a little edge. Knock off the box and play rhythm and hit the box on for lead work. A tubescreamer gives better sustain without sounding like an old Electroharmonix buzz box. It's a lot easier to get some nice violin-like sustain. But, if you're a shredder or into speedmetal the Tubescreamer wouldn't be your first choice.
I've done a few mods to the tone controls on my guitar and my weewah pedal too.
