First of all, thank you for following up with that information.As far as I know, the production Hollowbody, Archtop, SC-J and JA-15 models are all built in the same manner (no carved-in bracing. The PS Singlecut Archtop is the only model we've offered with the built-in bracing.
Would you please verify that about the SC-J? I'm pretty sure it's fully carved as well, like a clam shell, but I will admit, I got this second hand (from Larry of Angry Larry fame), and this was before you all came out with the Singlecut Archtop (either one, the spruce top one or the GotM maple top one), so it doesn't really make sense to me that he would describe that carving process -- with the bracing carved in -- unless it were the case. I would try and take pictures of the inside, but my photogra-fu are several orders of magnitude beneath yours, so I'd just embarass myself.
I'm asking because I kind of want my eventual private stock to be a 7-string singlecut archtop -- and the enormous bout on the SC-J just seems perfectly appropriate for to resonate even the lower strings, and carved-in bracing would provide the stability necessary for the additional tension.
