Hello,
I have the JP6 with a Piezo. 2008 model in metallic charcoal gray. It is a most excellent guitar for a few expected and then other nice surprises. I have a few guitars, this is the go to baby.
It is a very easy to play guitar. The purchase was based on playability, asymetrical neck is a very interesting design, and then of couse a most excellent Piezo pickup system. I believe it is one of the best offered. The tailpiece was a surprise on how good it works and it is resistant to going out of tune when playing live and one may get a little carried away by the moment and rest your hand on it. Very stable when touched or leaned on. Much better than my old Ibanez. The piezo pickup blends in stereo with the magnetic pups. Honestly, the neck pup and piezo come off with a STELLAR Knopfler tone. Dial in more of the neck pup and get the 'Telegraph Road' tone. There are bass/treble pots on the back of the guitar, very useful. I play a Boogie MKV and Rectifier live. The Rec gets switched off at the A/B/Y switch and the piezo can get too peaky for the MKV if you don't back it down on the guitar. That keeps it from compromising the tone settings on the amp. Handy. That Piezo & Neck pup combination is a sweet one, the kind that inspires one to take long solos and noodle a bit too much instead of practicing.
The stock pups are the best of all the stock pups I have at the moment. Ibanez RG, Fender USA strat (stock) Dimarzio Super Distortion in neck, Dimarzio X2N in bridge of 72 SG, ESP Skully KH model with EMG's.
I am going to swap out some pups for BK's but the ones in the JP6 are not candidates for swap. I have pretty much decided to get some Riff Raffs for my SG and Nail Bombs for the Ibanez RG. There may be some Apaches in store for the strat....
Peace,
