Slim, based on your experience ... what normally makes for a better cab?
1. One with denser, stronger wood for the frame to serve as a more stable "room" for the sound
or
2. One made of lighter, old and more resonant wood?
My bet would go to the more resonant old wood .... but if we were talking about heavier maybe metal stuff, maybe hte denser wood??
Better cab for what? It's difficult to say what's "better" without context. With what guitar, what amp, for what music, towards what tonal objective, how loud, how dynamic, in what venue... ad infinitum?
To be honest, I think all this talk about cab wood often goes a little overboard. It's minutiae. If you're gonna talk cab wood at all, IMO, the speaker baffle is also important and should not be overlooked. And there's a lesson to be learned there: Fender's baffle boards were made of plywood from 1946 to 1962. Particle board baffles debuted in 1963 and were used through the early 1980s. In other words, plywood/particle boards were part of that vintage sound. Did anyone complain then? Who insists on birch or pine used as the baffle board material for replicas of these amps? Builders who are trying to sell those cabs! And who believes them? Well, you get the picture...
If you really want a good sounding cab, it's the speaker that will make the most difference.
@firemodel55 - Is that on topic enough? If you wanted to be on topic in this thread, you should try the cab first and ask questions later. You'll be the wiser, even if it only reinforced your own dogma.
