size is the critical parameter. It needs to be as small as possible

Rane or Rolls single-rackspace line mixer
Mic of your choice
Mic cable, mic stand
Vocal processor of your choice
Baggs PADI
RNC
(I'd not bother with aural excitation, really; maybe BBE makes a unit
that's a DI + Sonic Maxmizer. But these things suck in general and I
can't imagine why you'd want to do that to a perfectly good signal from
a guitar.)
Patch cable(s)
Mackie SRM350, or two if you need them
Mic (XLRFXLRM) cable(s)
Ultimate Support TS90 speaker stand(s)
