I would think in the real world few people worry much about getting the matching factory cab?
I’ve been looking at the Marshall Sv20 vintage plexi style heads. They make a factory 2x12 vertical cabinet for it, but would I realistically buy that ? No, I’d much prefer a 70’s tall large check with some vintage GB’s.
Same thing if I was trying to find say a 80s JCM or whatever, would I want the match cabinet with v30s or g75’s or whatever they may have loaded it with ? Again no….. no a desirable style cabinet for me. I’d again with with a 70s large checkerboard with GB’s.
I’ve never once bought a head and the matching factory cabinet that I can recall. Have many people ?
I buy heads I like and pair them with cabinets I like, and/or already have.
I can only think most people do the same ?
As such, I can’t see how pairing an amp with a specific cabinet it was sold with is going to give the user some sort of tonal nirvana.
If anything, I think it could make people write off an otherwise great sounding amp because the cab it defaulted to sounds like hot garbage.
Same with a combo amp, if the stock speaker was crap and most people swapped it anyways, why default to something most people wouldn’t think sounds good right off the bat?
Get the virtual experience of taking out the factory speaker and virtually swapping it with something better ? Lol
Maybe I’m unique though, as I don’t care about keeping things vintage correct, I care about what sounds best to my ears
I don’t keep pickups in guitars I don’t like because that is how it came, nor speakers, nor tubes etc.
Don’t own a classic car but if I didn’t I wouldn’t care about keeping it all stock, I’d put the best go fast parts I can find in it.
