This is basically a brand new cartridge. The first photo is a stock photo but the rest are of the actual cartridge. I bought it and played one side of an album with it. Then my vintage turntable stopped spinning. Since I have to upgrade my turntable, I'm going with a standard cartridge mount, so I don't need this. Here's a chance to get a practically brand new cartridge for cheap! Free shipping too!The Grado Labs Green3 Prestige Cartridge uses a three piece OTL cantilever that has a Grado specific diamond mounted on a brass bushing. Grado’s OTL, or optimized transmission line, technology provides an ideal transfer of signal from the surface of the LP to the generator of the system. This technology rejects unwanted resonances and lowers distortion preserving the fundamental and harmonic frequencies of the music. This also helps keep noise generated by the motor system in the cartridge to a minimum.Grado’s OTL stylus/cantilever design makes records sound quieter, improves the height, width, and depth of the soundstage, and present more detail than previously obtainable.The Green3 is hand assembled by Grado's team in Brooklyn, with some builders having over 25 years of experience. This updated series of cartridges offers excellent tonal balance, dynamics, and realism, for a most rewarding reproduction of vocals and instruments. The coil winding techniques using ultra high purity copper wire, which were honed during the development of the Lineage Series, have let the electrical circuits achieve unison between the four coils in each phono cartridge. This allows for a precise balance between channels and accurate stereo imaging.As in all Grado phono cartridges the Green3 is powered by a twin magnet system that optimizes the balance between stereo channels. All internal magnetic circuit parts are held to extremely high tolerances creating the desired stereo imaging. Grado’s patented Flux-Bridger design allows the Green3 to have one of the lowest effective moving mass generating systems while creating an excellent balance throughout the full frequency range.

Generating expert take…
Grado Labs, a family-owned American audio pioneer, traces its roots to 1953 when Joseph Grado, a former watchmaker and Audio Hall of Famer, founded the company in Brooklyn, New York. Starting in his family's kitchen—once a fruit store—he and his brother John developed the world's first moving coil stereo phono cartridge, patenting it in 1959 and earning a reputation for precision engineering that propelled millions of units into recording studios and homes worldwide. Still handcrafting products in Sunset Park, Brooklyn, under third-generation leadership, Grado embodies enduring Italian-American ingenuity in high-fidelity sound.
The brand focuses primarily on phono cartridges and headphones, categories where it has defined benchmarks for decades. Early ventures included speakers, turntables, and wooden tonearms before concentrating on cartridges in 1963; by the late 1980s, Joseph Grado pioneered high-end dynamic headphones that rivaled top speaker systems in dynamics, pitch control, and bass. Today, iterative lines like the Prestige, Signature, "E," and "X" series deliver open-back designs prized for their natural timbre and detail, all assembled by hand without venturing into amplifiers, DACs, or speakers.
Grado occupies a niche boutique position in the high-end market, revered by audiophiles for its uncompromised, value-driven performance and vintage-inspired warmth. Free from corporate gloss, its handmade Brooklyn products command loyalty among discerning buyers seeking authentic vinyl playback and headphone immersion, blending collector appeal with modern relevance in an era of digital dominance.
