I know of two cabs that I'd be interested in looking at that come stock with V30s:
Mesa Traditional (Rectifier or Stiletto)
Is there anything else I should look for? I'd be buying this used probably.
Epiphone Del Rey Standard (EMG 85b/81n @ 18v)
B.C. Rich Mockingbird Special X (SH-6b/stock neck)
POD XT Live
Epiphone Valve Special
Old Peavey MS412
