Congrats Duff! As you know, I own and love my C-30. Very nice, articulate, warm and versatile tube amp that works great with pedals. Mine I purchased used, and it had Groovetubes (still does) in it. A lot of folks talk to Bob over at Eurotubes and re-tube them depending on taste. Their site has some info on it regarding some choices. But I would wait and see how you like it stock for a while.
Like TS said, some folks change out the speaker, but lots of folks really like the Blue Marvel. I like it myself. Really, a good, well designed and built tube amph for the price. Congrats!
