Well, that didn't take long. We're all giving you that knowing smile, Stu. It won't be long until you're struggling to decide which Guild strikes your mood today...
Rich's suggestion will certainly put you in another great Guild. But, you might be surprised, Stu, that an F-50R (rosewood, that is) sounds very different than the Guild dreads. It's my all-time favorite 6-string, so I always put a plug in for it. I guarantee you won't be disappointed with an F-50R.
That said, if you look around for an F-50 (maple) you might find one of the Standard models from New Hartford, which are not only fantastic guitars, but they are cheaper than the Traditional F-50 models (which are top of the line). Oh, and while I'm at it, there is a mahogany-bodied jumbo called the F-47 (I think) which wasn't produced for very long. I can't remember if this was a solid-backed or arched laminate. You could always look for an F-212XL and string it with 6 strings.
If you're looking for a smaller guitar, solid mahogany bodied F-40 or (I think) maple or mahogany F-30 will be great tonal changes for you.
Anyway, best of luck in the hunt. Definitely look for an "F-body" in your future.
