Ernie Ball Music Man JPXI-7 Review

Do you love John Petrucci’s Beard? Playing his guitars wont help you grow a beard like him, but it’s a start. One of the main things that made me want to check out the JPXI-7 is my love for my JP7.  So when I saw a JPXI-7 come up for trade in the Wired Guitarist gear exchange, I jumped on it.  I trade my JP6 PDN for my JPXI-7 and it was love at first play.  The guitar fits me very well being that I play mostly prog and alternative metal



The JPXI has a mahogany neck with ebony fretboard. The  body wood is Alder with maple top and mahogany Tone Block.  All these different woods in the guitar give it a very interesting sound.  It has a gloss finish with looks very nice in direct light.  It has a piezo pickup built into the EBMM bridge.  The bridge is one of the best parts of this guitar.  They are comfortable and rock solid.  Tuners are Schaller locking tuners, which are great, but the 7th peg tends to be too small for any string bigger than .59.  Making it a bite wider usually solves that issue.  Scale length is 25.5 and all music man guitars are made in California USA.  The stock pickups that come in the JPXI are the Dimazrio liquifire neck and crunch lab bridge pickups.  Mines came with a liquifire but my bridge pickup was a Dimarzio d-activator.  These pickups fit the guitar very well; the D-act was very tight and sounded great. Another feature of the guitar is that you can pull up on the tone knob and it splits the coils when the pickup selector is in the middle position.


Tone and Build Quality.


The JPXI can get a lot of different tones with his piezo pickup and single coil sound. The cleans sound very clear and glassy with the tone pot pulled, leads sound very smooth, and rhythm tones are very tight with the D-act.  The weakness of the guitar is that cleans on the neck pickup tend to sound very dead.  For the best clean sound, always use the split coil sound.


Build quality on the guitar is very good. The only issue I had on mine was a little finish swirling by the neck but it was very hard to see.  The stainless steel frets are very smooth, and even though it has a painted neck it is very quick and smooth.


Wrap up and Final Thoughts:


Being that I got my JPXI-7 used, it preforms very well in that $2k-1800 price range. I can play almost anything.  The only weakness I found with the guitar is that the cleans can sound a little dead when using the neck pickup, but pull the tone pot to split the coils in the middle position fixes that right up.  The only changes I would make to the guitar is to make it come in different stock colors.  It comes in an onyx color which is cool, but a red or even blue would make it look killer.  If I were buying new, I would go with either a mayones or an Aristides, only because you get more for your money.  If you are looking for one of the best American made mass produced guitars, it is very hard to beat EBMM.

This is the solo from Periphery’s song “Erised” that John Petrucci did a solo for. Playing this solo was very easy on the JPXI-7.
