Hohner Clavinet D6 (1971–1982): The Funk Machine That Bit Back

A German-built electro-mechanical keyboard whose staccato bark drove 1970s funk, rock, and jazz fusion. Part clavichord, part electric guitar, part percussion instrument.

The Hohner Clavinet D6 is a 60-key electro-mechanical keyboard built in Trossingen, West Germany, starting in 1971. Its tone was aggressive and very responsive to touch, and it often led a rhythm section instead of just filling it out. The Fender Rhodes Electric Piano has a warm, bell-like sustain. The Clavinet D6 attacked. Think of a gutbucket electric guitar run through a treble-heavy wah pedal and plucked with surgical precision. The sound was immediate and punchy, like a finger snap turned up to eleven, or a James Brown downbeat.

Stevie Wonder used the D6 on "Superstition" and "Higher Ground," where its staccato riffs carry the tracks. Herbie Hancock's Head Hunters album leaned heavily on its sharp attack, and Eddie Van Halen used it for texture on early recordings. The action is velocity-sensitive, so players could go from whisper-quiet plucks to snarling stabs just by changing finger pressure. That was rare in keyboards of the era. The D6 didn't imitate anything else.

Key Features

Velocity-Sensitive Electro-Mechanical Action: Unlike most keyboards of the era, the D6 didn’t rely on simple key contacts. Each key triggered a small rubber-tipped hammer that struck a tensioned metal reed—similar in concept to a reed organ or harmonica. This mechanical system translated finger velocity into tonal dynamics with startling realism. Play softly, and it whispers; dig in, and it snaps. This made it uniquely expressive, especially for funk players who needed rhythmic precision and dynamic contrast.
Four-Band EQ for Surgical Tonal Shaping: While many vintage keyboards offered basic tone controls, the D6’s four-band EQ (Bass, Low Mid, High Mid, Treble) was unusually sophisticated. It allowed players to dial in everything from warm, rounded comping to the now-legendary “quack” tone—achieved by cutting bass and treble while boosting both mids. This tone became the backbone of funk rhythm guitar before Nile Rodgers and Chic even hit the charts.
Built-In Vibrato Circuit: The D6’s vibrato wasn’t an afterthought—it was a lush, analog modulation that added depth and movement without muddying the attack. Engaging the vibrato transformed the D6 from a rhythmic tool into a lead instrument, perfect for jazzy solos or psychedelic textures. The 1976 Mk II revision improved this circuit for greater stability and smoother sweep.
Dual 1/4" Outputs with Normalled Configuration: The D6 offered two outputs that could be used in stereo or dual-mono setups. When only one cable was plugged in, the outputs were normalled (connected), making it easy to integrate into live rigs. This flexibility was rare in portable keyboards of the 1970s and showed Hohner’s attention to real-world usability.

Historical Context

The Clavinet D6 grew out of Hohner's earlier electro-mechanical keyboards. The Hohner Clavinet C (1968) and the upright Hohner Clavinet L laid the groundwork, but both had limited tonal control and were less portable. The D6, introduced in 1971, was the first to combine portability, expressive dynamics, and studio-grade tone shaping in one package. It answered the growing demand for stage-friendly, electrically amplified keyboards that could cut through loud rock and funk bands.

By the mid-1970s, the D6 faced competition from other clavichords and from the rising tide of analog synthesizers. The synths offered otherworldly textures, but they often lacked the organic attack and tactile feedback that funk and R&B players wanted. The D6 filled that gap: mechanical, immediate, and physical. It was followed by the Hohner Clavinet E7 (1977-1982), which added preset sounds and a more modern look but never quite matched the D6's raw character. Next to the Fender Rhodes Electric Piano, which offered warmth and sustain, the D6 delivered bite and decay.

Collectibility & Value

Today the Clavinet D6 is a prized relic of the analog era. In 2025, a fully functional, well-maintained D6 typically fetches between $2,500 and $4,500 USD, with mint-condition Mk II models at the upper end. It isn't extremely rare, but it is fragile. Fewer than 10,000 units were reportedly produced over its 11-year run, and many have succumbed to age-related failures.

The most notorious problem is the rubber hammer tips. Over time they degrade into sticky goo, and the instrument loses its signature attack. Replacing them takes a full re-tipping job, which is labor-intensive and can cost over $500. Crackling pots and switches are equally common, especially in the EQ and vibrato circuits, from decades of use and oxidation. The internal wiring is delicate, and grounding issues can introduce hum or signal dropouts. A buyer should test it hands-on: check every key for consistent response, listen for noise in the pots, and verify that the vibrato engages smoothly.
