The brand is most associated with the Quantum, a neck-through bass that became a staple for players seeking extreme stiffness, tuning stability, and a clear, consistent tone across the fretboard. Other models include the Quantum TBX, the bolt-on Modern J5, the Funk Unlimited and Funk Persuasion, and the Vintage J. A Flea signature Funk series, developed with Red Hot Chili Peppers bassist Flea, helped raise the brand's profile in the 1990s and 2000s before the line evolved into the non-signature Funk Unlimited.

Now operating under the Modulus Graphite name, the company continues to build small batches of handcrafted, American-made instruments. A signature visual detail on many Quantum necks is the "KLD" carbon weave pattern, a layered graphite finish the brand has used for decades. Modulus basses have been played by artists across funk, rock, and progressive styles, including Flea, Stu Hamm, Michael Manring, and Me'Shell NdegéOcello.

Modulus has 20 products cataloged on Equipboard, including Electric Basses, Solid Body Electric Guitars, and Modular Synthesizers. Their gear is featured by 25 artists, with the strongest followings in Rock, Metal, and Funk / Soul. Notable users include Flea, Bob Weir, and Divinity Roxx.
