General
Back in the day, heavy metal was often played in standard tuning. Times change, though, and so does music. Corey Beaulieu, lead guitarist of the band Trivium, plays a 7-string guitar. That extra low B string, in combination with the powerful active Seymour Duncan Blackouts, offer everything you need for reeking some pure metal havoc. The KV7 is visually attractive with its extra pointy King V body in matte black, and a reverse pointed headstock, making this Jackson a mighty weapon in the battle for artistic freedom of expression!
Corey Beaulieu X Series KV7: high playing comfort
It may take some time to get used to a 7-string guitar if you've never played one before. Still, the Jackson KV7 is surprisingly easy to play. This guitar's neck has a satin finish, which remains smooth to the touch and allows for fast playing even with sweaty palms. A remarkable feature is that the KV7 has a standard scale length of 25.5 inches, making it easier to handle than a baritone 27-inch scale length, for example. This also means, however, that the low B string is not as tight, but that can be compensated with a thicker string.
Compound-radius fretboard
The KV7's dark rosewood fretboard has what's known as a compound radius, just like the more expensive Jackson USA models. Near the headstock, the fretboard is quite concave (12-inch radius), but when you near the body, it flattens out a bit (16-inch radius). The result is that both barre chords and open chords are comfortable to play. That's not all, however; even at extra low action, you can still easily push strings up on the higher positions without unwanted sounds or tones getting cutting off. A flatter fretboard is also ideal for techniques like tapping.
