Hey Carvin X100B owners! Can you tell me the difference between the earliest model X100B's with the black tolex covering and the chrome corners and the later gray carpet covered model X100B's? Or are they basicly the same amp? Is one better than the other? Seems like I remember the earlier one had a slightly different layout on the controls. I'm looking to buy a gray carpet covered one that has a larger "Carvin" logo than the originals. Played thru it today and it sounded pretty good. Only problem is it doen't come with a footswitch. It's a three pin input that looks like it takes a mic cord with a cannon type end. Does anyone know where I could get an original foot switch for this amp if I end up getting it? Thanks for any info. Guys!!
