I used to have a Guild JF65-12, which is the upscale cousin to the JF30-12.
The tone from a vintage Guild 12 is like a chorus of Angels singing background while you play a vintage Guild 6-string.
Not only that, but a vintage Guild of any type is likely to be a canon, and and will be built so solidly that you could use it as a weapon to bash an onslaught of zombies in their squishy heads after which you could sit down and play with the guitar still in tune.
My main acoustic is a Taylor (shhh - don't tell my Guild buddies), and I absolutely love it, but I like it because of its modern bright timbre. I also baby it because it feels like it's made of balsa wood. A vintage Guild - especially a big 'ol 12-er - will likely weigh substantially more than your Taylor, and will have a much deeper voice. The kicker about vintage Guilds is that they have a deeper voice but still ring out with articulate clarity that makes grown men cry.
These JF guitars are BIG, so be prepared if you've never played a jumbo. Big is good, though, especially if you need to battle zombies with your guitar.
