Thanks for the reply Simon, I was considering DMing you for advice but it seems there's no need
It's the GMS7Q multiscale, I know that it comes from a factory that pitbull have little to do with so I assume they're just passing on the boxes, but yes this should be checked it's still their product.
I chucked them an email earlier and I'll see what I hear back, because ironically I was considering purchasing a second kit because up until now I thought the finish issues were relatively minor for the price (body filler, veneer chipping, wrong veneer on the headstock, too wide a neck pocket etc.), but a whole missed routing is pretty bad lol.
I was actually considering getting a barrel jack to minimize how much I have to chunk out of the body, I'm not sure I have a 7/8" bit anywhere, but a barrel sized hole I could get done with just a regular straight bit.
Because of how my schedules been, we actually have the guitar fully finished and cleared, I was too focused on the neck pocket to notice the lack of a jack routing apparently, no idea how we missed it.
