I’m Sergey Kasinec and I have been playing a guitar and composing music for more than 15 years now. I have had so many guitars and have reviewed a lot of guitar gear. In my introductory post on Guitar Sphere, I’ll be reviewing my MusicMan JP7.

Feeling-wise, I had always been in love with Floyd Rose before I met Music Man® floating tremolo. They let me do all the tricks which I used to do with a Floyd Rose but in much easier way. It takes me no time now to change the strings. There’s no string lock on the neck and still the guitar is always in tune although I use Tremolo all the time. Tremolo here works unbelievably smoothly and the feeling is just amazing.

The neck is not coated and the thickness of it is just perfect. It lets my fingers fly around the fretboard and extract sound clearly and effortlessly. It’s so easy to play on higher frets and to perform any shredding with this baby!

When you take this guitar into your hands, it feels so natural because of the special recess in the body under your right arm. As comfortable as can be.


My favorite pickups have never let me down, be it some beautiful tunes or some really hard metal riffs. The clean sound here is open, bright and warm. The sound is actually that very thing to make me fall in love with this guitar (I was listening to JP’s Suspended animation at that time). It’s very deep, it cuts through the mix both in studio and on rehearsals. So recognizable.


I am absolutely satisfied with this guitar. Its sound possibilities are endless and its majestic beauty mesmerizes. This guitar inspires genuine love once you have it in your hands.

Whether it’s the pickups, the wood choice or the overall build of the instrument, everything here screams about the awesomeness of this mystic beauty.
