I've been trying to find a channel switching amp that will do the Marshall/Fender/Vox and guess what? no channel switcher will ever give me what I really need, which is a Marshall, a Fender and a Vox. I've decided to go for the real thing, but I'm concerned about reliability on the road. I'm thinking I should go the head/cabinet route and isolate the heads in their own road case. My reasoning is that the least amount of vibration should help insure some reliability. I also plan to make sure the heads are well ventilated and will install fans to suck hot air out. All the amps will be completely gone over and any components that need replacing, will. My tech will be required to carry spare parts for the amps in case of any problems. Each amp will be tested pre and post gig. Also, the tubes will be constantly checked and biased if need be. I think with enough preparation, I should be ok. I'd still like to hear from those of you that have or presently gig with vintage gear. The amps I've decided on are as follows. Late 60's/Early 70's Silverface Bassman or Bandmaster w/4x10 open back cab. 73' to 76' Marshall 50 watt head and cab Early to Mid 60's Vox AC30 head and cab thanks for your help.
