According to me, Ibanez makes really versatile guitars. More than that, they are great to play on. The ibby's thin neck, though not for all, is extremely comfortable and has a great feel. The quality of the components, especially at the prestige level is top-notch and very few brands can compete with them. Regarding the 22 fret guitars, I have found them rather irritating if u have played a 24 fretter. I dunno about the "sweet spot" your talking about. Though ibanez's aren't made for blues, it is not difficult to get the required sound. But realistically, if your into blues and jazz, you should probably get a fender strat. They are great, albeit expensive. If you wanna get a les paul, for the love of god, dont get the low-end epiphones. They are a joke. The av-6 also is average to say the least. If your only spending 20k on the guitar, I highly suggest you goto a guitar store and play a rg321.
