I think it's mostly cosmetic. The 7593 looks somewhat like a Baldwin era guitar, has block inlays on the fingerboard, a V-cut Bigsby and parallel bracing with a soundpost.what are the fundamental differences?? i can't find any info on them. i know this isn't an electromatic question so i apologize, but there seems to be zilch on this topic.
Trestle bracing is less likely to feedback and more focused sounding.thanks guys that leads me to a few more question lol!
so it seems like the differences are primarily cosmetic, but are there any tonal differences? i noticed that all the white falcon owners on this forum favor a 6136 which i know is slightly more expansive, any reason why? also how does parallel bracing compare to trestle? a tall order...lol
