I've gone for the Vibro Champ XD after noticing that it has both pre-amp and power-amp tubes, rather a hybrid style amp over the solid state nature of the Mustang. Should arrive tomorrow, so I'll boot her up and let you know how I get on.

Apparently the only difference between this and the Super Champ XD was that it's 5w rather than 15w and so got discontinued due to lack of demand. I find that hard to believe as BlackStars HV5 and HV1 are doing very well. Perhaps the profit margin wasn't so high compared to the Mustangs and the Super Champs? Anyhow can't wait. NGD tomorrow!!
