Jackson - Pro Series Signature Jeff Loomis Soloist SL7

MSRP: (UK) £1377 / (US) $1699

The Jackson Pro Series Jeff Loomis Soloist SL7 is not only for Arch Enemy fans—it would be a huge asset to the serious Metal guitarist who requires a precision instrument. It is an especially good choice for the touring musician but will fare equally well in the studio, especially when paired with a high gain amp. Rodney McG Tells us more.

The Jackson SL-7 7 string soloist is the signature model of guitar virtuoso Jeff Loomis. Loomis is known for his instrumental albums as well as being a member of prominent metal bands Nevermore and Arch Enemy. Needless to say, this guitar is based around fast playing and straight to the point, aggressive styling.

The build is a Basswood body topped by a sandblasted Ash face. It's a solid Maple neck through the body with graphite reinforcement. The Sl-7 also has a full-body, fretboard, and headstock binding with matching Ash faceplate on the headstock, as well as a raised chrome Jackson logo. The traditional Jackson shark-fin mother of pearl inlays is also on board with the ebony fingerboard.

The pickup set is dual humbuckers in black chrome from Seymour Duncan, also a Jeff Loomis signature model. The tremolo is a 1500 series Floyd Rose. The neck is slim and definitely designed for fast playing and shredding. Combined with a compound radius going from 12 to 16", it makes for an extremely flat profile that also lends itself to high speedrhythms, riffing, and lead work.

Teamed with the pickups is a no-nonsense electronic setup consisting of a single volume knob, no tone controls, and a pickup selector. Direct and to-the-point and making the sound of the pickups clear and without excessive options to dull the output.

The 1500 series tremolo held up well and after a bit of string stretching, it played accurately and stayed in tune even after some heavy whammy abuse.

The overall tone of the guitar came across as balanced, with very throaty sounding mids that didn't quite sound like other pickups from the genre. It had solid clarity, and slightly rolled off high-end cutting out excessive harshness under High Gain applications, which is very likely what anybody looking into this guitar is going to be using it for.

The neck pickup added the bubbly rolling sound you traditionally are going to look for in a lead tone, but being active kept it articulate and without the excessive mud that can be common for pickups in that position.

The guitar balanced well, and wasn't as light as you might expect from other Basswood guitars you may have experienced. Likely due to the fact that it has not only the maple neck through the body strip, but the Ash top likely helps give it some substantial feel. While not a heavy guitar, it doesn't have the excessively light or cheap feeling that many Basswood guitars can have. The Jackson Sl-7 is a true shred machine from top to bottom designed for one thing specifically, and it delivers on that one thing extremely well.
