It would depend on why you want Jumbo frets? If you are having trouble hitting or holding down strings there are ways around this, if, however, you want them for other reasons then look towards a classical guitar. Yea, I know, nobody likes classical guitars...wimpy...but, I'll never trade my Ovation classical away. I value it as good as my American Fender and higher than my Epiphone Dot.

Make sure Jumbo frets are really what you want. Try playing on different necks from the "V" of the Fender to the "U" of the Gibson/Epiphone. You might also want to try a lighter strings on your current model.

My two cents, anyway.
