Just a thought but, With the often-used adjectives of, "Honky'-Hollow" along with all the speaker swapping... it makes me wonder how many of you check for proper wiring polarity, when you acquire these cabs?
I personally tear down every cab that enters my studio that I buy. which is often new out of the box. I rewire and make modification to each cab as well. and in doing so, I have discovered 2 of the brand-new marshal 1960B's were improperly wired, and one (out of the box) celestion speaker that was wired backwards. (I test everything, as most things are built by people that make low wages and don't care) I worked in factories for 30 years.
Being someone who records almost every day and is often surrounded by those that do the same.... anything that is out of phase, gets quickly picked up on as everything I record goes through phase checkers, spectrum analyzers and my ears a pretty seasoned for such things. I've had a fair share of client cabinets come in sounding funny, and when I pop off the back Pannel...I can quickly see that the problem is most often improper wiring. (is why I started collecting cabinets)
I have OS and traditional mesa cabs that sound incredible under the mics so, I wonder about the ones that are mentioned on this thread?
