@Exo-metal recently picked up an Atlas cab for a song recently; and he LOVES it. These small builders usually do great work and when one comes up for sale, go for little money. You could check them out as well.
The one feature in the late 67-68 Marshall cabs that no other year had is, a long brace that ran the length of the baffle on the bottom of the cab. In 69 that disappeared and they used small wood triangles. The Atlas cab, and vintage Orange cab I have uses that brace as well.
Thanks a ton for sharing this! I had no idea about the long brace in late '67/'68 Marshalls and the small wood triangles in '69 models.
It’s really helpful to hear how this translates to the cabs I’m looking at: MGL uses the long brace, while both Metropoulos and Germino go with the small wood triangles.
Yes, lots of small variations over the years; I've also had a couple of '68 cabs especially that were really fantastic sounding and raised above most of the few 10s of other old 4x12 I've had over the years.
That being said, I've also had earlier and later cabs with slight different "specs" that sounded fantastic and just as "good".
In other words: I'm not really sure that one can relate between some specific isolated construction details like say, that lower internal front baffle bracing spec, and the end result how the cab sounds & feels playing it. In a "statistically representative way" I mean.
Earlier Pinstripe cabs didn't have that lower bracing, actually no lower bracing at all. Doesn't mean they don't sound fantastic. Same with the later Basketweave / early Chequerboard.
I even have a counter example in mind, from first hand experience:
I had a '70 1982B cab, with the bass cone G12H30 speakers, fully original besides a so-so recover job; no lower internal bracing at all; sounded absolutely fantastic and was my main band duty / gig cab for years over 20-25 years ago. Years after that, I had the "brillant" idea to swap the speakers in an earlier very nice '68 B cab that was 100% original, thinking that would make for a "better cab" overall.
Guess what? Sounded not as good as the '70 cab.
Another example: the only 2 old Marshall cabs I've ever had that sounded close enough, so that I could not really tell the difference switching between them, were 2 slant with G12M lead: one was a '68 (with the long lower bracing discussed above) with original speakers, the other a later '69 (with the "small triangles" bracing) in which I had assembled unmatched speakers gathered over time.
