From Music Man:

Celebrating three decades with Grammy award-winning guitarist and signature artist Steve Lukather, the Ernie Ball Music Man company is proud to announce the arrival of the new Luke 4 SSS signature guitar. This fourth installment in the Lukather signature line of instruments features a roasted alder body with a figured roasted maple neck and rosewood fingerboard. The Luke 4 is outfitted with custom Music Man pickup technology, delivering an incredibly dynamic and responsive playing experience. The pickups can achieve an ultra-high-output, powerful, low-end response while retaining a distinctively clean, clear tone at lower volume levels. The Luke 4 SSS shares many of the standard specifications of the original Luke guitars, including a double-cut contoured body, a roasted figured maple neck, 22 nickel frets, 5-way switching, adjustable 12db boost, a Music Man vintage floating tremolo, and ships in a Mono case
