You might want to look at sticking a re-verb unit into the FX loop.

It is good to remember that re verb has to go after distortion or it will sound like crap !

You might also want to look at getting some JJ audio tubes (Euro-tubes, their is a link on my instructors page). I have some for my TSL however I'm waiting till Xmas to put em in so I can make a job of it with no one home down stairs !
