And that's not even the tip of the iceberg.
First you have to find the cabinet and buy it, which is not easy or cheap at all. Then you have to pray so both they are originals, and not re-covered or re-coned. Once that's settled, you have to pray so both the cab sounds good and the speakers are healthy. If both are good, and they sound great together, THEN you'll have a great sounding cab. Problem is, most likely you will, sooner or later, find another one of the exactly same that sounds better, and you'll start all over again.
Since 1998, I've owned and sold, easily, more than 40 basketweave cabs, to personally play, inspect and listen to all of them side by side, and cherry pick what I have.
Same with amps and guitars.
Not cheap or easy at all, but I finally can enjoy the gear I always wanted, and not have to wonder about upgrading it.
Is it worth doing it? To 99% of people out there, absolutely not. To me? Worth every minute and every cent I've worked for and invested on.
Again, I'm the exception here.
