Super Champ XD Tube options

Hi, love this little amp, but was wondering how to "warm it up a little" It has beautiful brights with my tele on the bridge and middle settings. I would like to smooth out the sound a bit. I currently have a 10" rajin cajun as my first upgrade. What would you suggest for tube sets? Any experience in upgrading any or all of the stock tubes in it would be appreciated.
Thanks FF

Check this thread. Lotsa good info there. I just posted my experience this morning.

wrong forum, but I put JJ's in my VCXD and it sounded a ton sweeter, and louder...
