MusicMan JP Koa

The John Petrucci Sound

He’s a god amongst guitar players. John Petrucci is perhaps best known for being the guitarist of Dream Theatre, although his influence extends far beyond the band. Having exhibited extreme mastery and skill when it comes to guitar playing, he has inspired guitarists around the world and secured his place in history as one of the greatest guitarists to have ever lived. The John Petrucci signature model has been inspired by his playing style and personal specifications, so you'll find it is as near to perfect as you can get.

Show-stopping sound

Tonal finesse. The Liquifire humbucker in the neck and Crunch Lab humbucker in the bridge have one thing in common – they sound superb. The LiquiFire’s name says it all – Free flowing, volcanic tones erupt from this spectacular pickup. It has a boosted midrange response with a tight low and damper, cleaner highs. The result is a beefy, punchy sound which is perfect for flowing lead lines with the gain turned up, and clear, defined chords on clean settings. And the Crunch Lab matches this, with a high output and crisp, detailed articulate twang. It’ll bring your chugging to life with high gain settings, and easily cut through any mix.

But let’s not forget the John Petrucci signature’s secret weapon – the piezo pickup. Most guitars can’t even come close to replicating acoustic tone – not this one. The piezo pickup sits under the bridge and adds blissful, chiming, authentic acoustic tones to your arsenal. You’ll be able to push your creativity to the limit.

Supersonic neck

Play at breakneck speed. Take your guitar skill to the top with the incredible neck profile of the John Petrucci. It is made from select maple, so it adds tonal brightness which will naturally emphasise the attack and bite of the notes you play. Being finished with gunstock oil and a hand rubbed special wax blend, it is silky smooth, facilitating the slickest, quickest fretboard manoeuvrability imaginable. The fretboard is made from luscious rosewood, which adds a touch of warmth to the neck’s brightness and feels sublimely smooth and responsive underneath your fingers. Play without limits.

Basswood Brilliance

Resonant and resilient. This guitar has a resonance which rings out powerfully, with the basswood body offering both warmth and brightness. It effectively emphasises the mids, giving your tone more crunch and clarity. Its lightweight nature also makes it incredibly comfortable, and each contour is designed to fit around your body. The scooped arm contour also gives you ample comfort, so you'll find this instrument incredibly easy to play.

Solid tuning stability and endless vibrato

Everything you’ve ever wanted. Boasting Schaller M6 locking tuning machines, the John Petrucci signature will rarely go out of tune – if ever. They keep your strings locked in place, and also making string changes much faster and simpler. They’re coupled with the premium Custom John Petrucci Music Man floating bridge, which also keeps your strings firmly in place and maximises your sustain. But that’s not all – it also lets you inject your riffs with ludicrous (or subtle) amounts of vibrato, so you can fire out screaming divebombs at will. Are you ready to experience musical enlightenment? Good. Then get ready to shred on this supreme model.
