I did/do not have a 700, but do have a JTV-69K (and just purchased a JTV-59PG), I use an HD500 at my weekly gig (7 hours of background music) and the 69.  The flexibility it gives me is fantastic and the combination of the HD and JTV is magical.  I do play through FRFR (QSC K10s) and venue/set is mostly soft jazz standards, classic rock, some country and blues.  For this I use the 335/L5 for most, the strat and tele as well as acoustic (6/12) for eagles and boston...

It (the combined JTV and HD500) is a great combination and I highly recommend it.  I'm switching to the 59 due to a better fit for this use (don't use the tremelo that much, want the better neck of the 59).  May sell or just keep the 69 (need to replace the neck...has the 1st string issue and frets are worn alot).

I've had a 700trem since 2003, bought a 300 as a backup 5 years ago and bought a  JTV69s about 2 months ago. Overall, I think it is a better built guitar than my 700. The new features are very nice and while the mag pickups sound good, I've always hated the single coil hum. So at some point, I'm probably going to put Kinman noiseless pickups in it. Is it as nice as a PRS, Suhr or other highend guitar - no -, but my Variaxes get almost all of my playing time and have for almost 10 years. 

Edit -  Oh, I also really like the neck on it. I know that others have had problems and the shape style or whatever isn't right for them. For me, I like the neck better than my 700. And its GOLD!!!
