D&D Custom Guitars is a Manila, Philippines-based instrument company founded by Daren Sy Lim and Daniel Crisologo, with the brand name derived from their initials. The company designs and distributes electric and acoustic guitars, basses, amplifiers, effects, keyboards, percussion, and studio gear, positioning itself as a homegrown Filipino alternative to imported brands at a more accessible price point. Daniel Crisologo leads design, while guitar builder Christian Callanta oversees construction at the company's overseas factory.

The brand is best known for its D&D Signature Series, which includes artist signature models developed in collaboration with Filipino musicians — lines such as the KIDLAT and AURORA series, alongside signature guitars for players like Jugs Jugueta, Jian Lubiano, and Joko Reantaso. D&D operates retail locations across the Philippines under the D&D Store banner and sells directly through its ddmusic.ph storefront.

The company has built a large artist roster within the Philippine music scene, with endorsers including Manuel Legarda, Darius Semana, Gabriel Cheekee, Wally Gonzales, Carlos Tanada, Paul Yap, Bullet Dumas, and Inky De Dios. Its identity is tied closely to the local scene — marketed as a Filipino-designed brand aimed at both working musicians and beginners.

D&D Custom Guitars has 10 products cataloged on Equipboard, including Solid Body Electric Guitars, Electric Basses, and Acoustic-Electric Guitars. Their gear is featured by 4 artists, with the strongest followings in Rock. Notable users include jomal linao, Pakoy Fletchero, and Steve Badiola.
