Interesting comments from Jim and Neil. Alan McK used his XD at our last gig (a charity 'do' in a hotel ballroom) and had no problems being heard over drums, bass and my Valvetronix. The point of acquiring one was to replace the Vox which is a bit heavy to lug around so going for a bigger Fender than the Super Champ wouldn't address that need...
On the back burner in the meantime.
