I have a Vibro Champ XD that I like pretty well as a practice amp, but I am thinking that a bigger speaker will make it sound better. It has an 8" speaker in it. I know some folks have replaced the stock speaker with a Jenson P8R or C8R and like the tone a little better, but it looks like there is room to put a 10" speaker in there (another 1" all around). On the Super Champ XD amps, most folks really like the Rajin Cajun speaker, so I was considering putting one of these in the VCXD. Anyway, has anyone tried a larger speaker in the VCXD? Have you plugged it into a cabinet with a 10" or 12" speaker? If so, how did the sound change? Any other good mods for this little amp?
