Rombo is a Germany-based guitar pick company founded by Judith Heindorf and Carlos Diez Macia, a husband-and-wife team operating out of Remseck am Neckar, near Stuttgart. The brand launched through a Kickstarter campaign in 2019 with four initial designs and has since expanded to a lineup of over a dozen distinct pick models, each with a unique sculpted shape, microtexture pattern for grip, and variable thickness profile. Raw materials are sourced from Italy, and manufacturing uses injection molding in Germany.

Rombo's catalog spans a wide range of thicknesses and playing styles, from the flexible Classic (0.45 mm) to the hefty Jade (2.3 mm). Core models include the Horizon, Prisma, Crisp, Diamond, Origami, Waves, Erebus, Mosaic, Shell, and Dune. Many feature variable-thickness bodies — a thicker holding area paired with a thinner tip — designed to combine the warmth and control of a heavy pick with the attack of a lighter one. The brand also offers CrystalBright, a hand-polished material engineered for brighter tones and durability, and the EcoBlack line, made entirely from 100% recycled pre-consumer fiber waste. Accessories include rubber headstock-mount pick holders and strap blocks.

The company has been featured in publications including Premier Guitar, Guitar World, MusicRadar, and Bass Musician Magazine. Rombo maintains an international dealer network spanning Europe, North America, Asia, Australia, and South America.

Rombo has 5 products cataloged on Equipboard, including Picks & Pick Holders. Their gear is featured by 1 artist, with the strongest followings in Rock and Blues. Notable users include Nicole Cerminara.
