Cabs are like amps. No two cabs, even from the same manufacturer, will sound the same. At this time I have 2 JCM 800 slants, both loaded with 80s Marshall Vintage speakers. They are my fav cabs ever, even over some vintage Marshall cabs(79 w/65s, and a 72 w/pulsonic GBs). I also have an EVH cab with Heritage 20Ms. 2 JCM 900 straights, both with greenbacks and 2 of those GBs are 1966 H25s.
2 empty cabs, one Mode 4 B cab, and a 1968 Sound City straight cab that I got (empty) in a trade for a Boss SD1 lol.
I've also had 3 Mesa half backs, with EVs/C90s, all EVs and one with MS12s. 3 Mesa V30 cabs, 2 traditional and 1 OS. 2 Bogner V30 cabs, and 1 Rivera V30 cab. If you want a V30 cab that hits equally to the Mesa Traditional look no further than the Rivera K412s....that Rivera cab sounded identical to the Mesa V30 cabs. They also came with 75s.
Had a LynchBox cab as well, another great cab IMO. Came with an Eminence version of a GB. Hard to find though.
The most disappointing cab I had was a VHT Fatbottom cab with those P50s. Worst fn tone ever. Read up here on how great it was supposed to be...absolute garbage. Couldn't return that cab fast enough.
