Nebelung Guitars is a Norwegian electric guitar company founded in 2002 by designer and builder Ronnie Nebelung, based in Horten, Norway. The brand is built around original designs featuring Korina tonewood across the entire lineup, paired with Wilkinson hardware and a proprietary bass-cut control that allows players to dial back low-end frequencies for added tonal versatility. Production guitars are manufactured in Korea at the same factory that builds Reverend guitars.

The Riffmeister is the brand's flagship model, blending sharp retro-inspired curves with modern body contours and available with P-90 or humbucker pickups. The Chordette, another model in the range, features Filtertron-style pickups and a bolt-on neck design. The guitars have found a following among Norwegian rock and metal musicians, with players in bands such as Kvelertak, Honningbarna, and Seigmen adopting the Riffmeister as part of their rig.

Nebelung has 7 products cataloged on Equipboard, including Solid Body Electric Guitars. Their gear is featured by 2 artists, with the strongest followings in Rock, Pop, and Metal. Notable users include Bjarte Lund Rolland and Paul Waaktaar-Savoy.
