Okay, okay, I'm sorry I said that neck shape preferences are nonsense. I'll repeat that... I'm sorry I said it. I never get anywhere saying that anyway. All the musicians I know play multiple instruments... guitar, bass, fiddle, banjo, mandolin, keys, and non of the discussions we have ever mention neck shapes. So for me and most of the musicians I hang with, it's a non issue. BUT... Guys who think the neck shape is important are not going to change their minds. So I should have deleted that part of my post. Because I really did want to welcome the OP, and I really wanted to answer his question if I could. I said above that the SGJ is an excellent and inexpensive Gibson. I said above that it has lots of potential. For me, that's important. For a left handed player who has less choices, it seems important to me. IMHO the difference between the SGJ and Gibson's more expensive models comes down to cosmetics... You pay a lot more for Inlays and the legendary Gibson Deep Gloss... Does the gloss make the neck feel different? Yes. Is that important? not to me. I usually scrub the back of my guitar necks with a green kitchen scrubbie, especially the Polyurethane ones. I like the gloss on the back of the neck of my '18 J-45. So I haven't scrubbed that. I can't tell you if a more expensive glossy neck will be easier for you to play or feel more slinky, or if the non-glossy finish of the SGJ neck will be easier for you. I think that goes down to setup and string gauge. I think ALL SG necks are fast and comfortable. But if you've never owned one... Maybe you don't. One more difference between the SGJ and an SG standard is in the bridge pickup. SGJ has the 490R/490T pickups... the Standard has a hotter bridge pickup. The first SG I bought had the 490s, and I played it for about a year and learned how to get the best out of the 490s, and then I saw Gibson '57 classic and Classic plus go onside, and I replaced them. I'm much happier with the tones I get from the '57 Classic plus than I was with the 490T. The reason I said you have to play it is because you've never owned an SG. I know nothing about your music or your preferences, so I can't make an opinion about which would feel better. I love SGs and they all feel great to me. But if you have a collection of Strats and shredders, the SG will feel different. I'd pounce on that SGJ, and get it set up by the best luthier you can find or afford.
