AMSynths AM8060SE JP6 VCF (2010–2023)
Plug this 14HP beast into your Eurorack and suddenly, the growl of the '80s isn’t just back—it’s got a new home.
Overview
If you’ve ever chased that Jupiter 6 filter tone—the one that snarls on the way up and purrs when it lets go—you’ve probably resigned yourself to paying vintage synth tax or wrestling with software emulations. But AMSynths quietly flipped the script in late 2010 with the AM8060 JP6 VCF, a Eurorack module that doesn’t just nod to the Roland classic—it surgically replicates its heart. This isn’t a vague homage or a “vibe” clone. It’s an exact circuit-level recreation of the Jupiter 6’s voltage controlled filter, scaled down to 14 HP and built for the modular age. And when AMSynths re-issued it in 2023 as the AM8060SE, they didn’t just reprint the old boards—they refined it, tightening up the resonance control and giving it a sleeker, more authentic look with red LED sliders and original-style Roland JP-6 momentary buttons. It’s rare to see a module that feels both like a preservation project and a practical tool, but this one bridges the gap.
The AM8060SE isn’t trying to be everything to everyone. It’s focused: capture the character of a specific, beloved analog filter and deliver it with reliability and precision. And based on owner feedback, it nails it. One reviewer, Alan Maxwell, called it “really terrific, as characterful as I hoped for,” noting it handles both modern sound design and “old school vibes” with equal ease. Another, Thaneco, put it more simply: “The sound of this filter takes me back to the 80s. Very well built and one of my favourite!” It’s not just the tone—though that’s the headline—it’s the build, the attention to detail, the way the red LEDs glow under your fingers like embers. This is a module made by people who care about how things feel, not just how they measure.
But let’s be clear: this isn’t a filter for the faint of heart or the minimalist. It’s got weight—300 grams of dense analog circuitry—and it demands space. At 14 HP, it’s not the widest thing on the rack, but it’s not subtle either. And while it’s currently in production, earlier runs were extremely limited. The 2014 revision of the original AM8060? Only 30 units were made. That scarcity has earned it a “rare” label on secondary markets, where even bare PCBs have sold as collectible items. So while you can still buy a brand new AM8060SE today for £160, you’re not just buying a filter—you’re buying into a small-batch legacy of obsessive replication.

Key Features
Two SVFs in series: the secret to that Jupiter 6 bite
The core of the AM8060SE’s sound lies in its topology: two 2-pole State Variable Filters (SVFs) wired in series. This isn’t a standard 4-pole low-pass like you’d find in a Moog or a Jupiter 8—it’s a more complex, flexible architecture that gives the Jupiter 6 its distinctive edge. Each 2-pole stage can be switched independently into either Low Pass or High Pass mode, which opens up three usable filter configurations: a 24dB/octave Low Pass, a 24dB/octave High Pass, or a 12dB/octave Band Pass (with two variations depending on internal routing). This flexibility is a big part of why owners report “a lot more flexibility in sounds” compared to simpler OTA-based filters. And that’s not just marketing—this design inherently allows for sharper transitions and more aggressive tonal shaping, especially when resonance is cranked.
No self-oscillation, but plenty of bite
One thing to note: this filter does not self-oscillate. That’s a deliberate design choice, consistent with the original Jupiter 6 filter, and it’s confirmed in the product documentation. While some modern filters use self-oscillation as a sound source or tuning aid, the AM8060SE stays true to its source, focusing instead on coloration and resonance within the passband. The resonance is variable across all modes, and the 2023 re-issue includes a revised resonance control circuit that reportedly smooths out the response and improves stability. Owners who’ve used both versions note a more predictable sweep and less tendency to get “hot” in the upper ranges. It’s a subtle but meaningful upgrade for live performance or precise patching.
Layout that feels like home
The control layout strikes a balance between Eurorack practicality and vintage homage. The INPUT MIX knob blends two audio inputs—a useful feature for layering or parallel processing—while cutoff and modulation are handled by slide potentiometers with red LED level indicators. These sliders aren’t just for show; they’re tactile, precise, and visually intuitive, making it easy to see your settings at a glance. The KYBD, LFO, and ENV modulation sliders let you shape how the filter responds to control voltages, and since the CV range is typically 0 to +10V, it plays nicely with standard modular gear. Resonance is adjusted via a rotary knob, keeping that critical parameter under firm, continuous control. The 2023 version upgrades the sliders to red LED types and adds momentary switches with red LEDs for mode selection—details that make the module feel more like a premium instrument than a DIY kit.
Built with reverence
The AM8060SE doesn’t just sound like a piece of history—it looks and feels like one. The 2023 re-issue uses black aluminium control knobs and, crucially, original Roland JP-6 momentary buttons with LEDs, salvaged from decommissioned units. That’s not just nostalgia; it’s a commitment to authenticity. The Rpar AS3109 chips serve as modern equivalents to the original CEM3340-based design, ensuring reliability without sacrificing tonal accuracy. And while the depth of the module isn’t specified, the included Doepfer power cable and M3 mounting hardware mean it’s ready to drop into any standard Eurorack case right out of the box. It’s a complete, thoughtfully packaged solution—not a bare PCB you have to source parts for.
Historical Context
The AM8060 JP6 VCF exists because the Roland Jupiter 6, launched in 1983, had a filter that never got its full due. Overshadowed by the Jupiter 8’s smoother, more polished character, the Jupiter 6’s filter was sharper, more aggressive, and less forgiving—qualities that now read as character rather than flaws. AMSynths didn’t just sample the sound; they reverse-engineered the actual filter circuit and repackaged it for the Eurorack format, launching the module in late 2010. At the time, the Eurorack scene was expanding rapidly, but faithful analog clones of vintage filters were still relatively rare. The AM8060 filled a niche for players who wanted that specific Roland texture without the bulk, cost, or fragility of the original synth.
The comparison to the Jupiter 8’s 4-pole OTA filter is inevitable—and telling. Reviewers and designers alike note that the AM8060’s sound is “more aggressive” than the Jupiter 8’s, thanks to its dual SVF design. Where the Jupiter 8 filter is warm and rounded, the JP6 VCF cuts through with a grittier, more dynamic response. This isn’t a clone of a clone; it’s a direct extraction of a unique analog voice. The 2014 revision refined the resonance circuit, and the 2023 re-issue brought it back into production with updated aesthetics and improved build quality. It’s a module that’s evolved, but never strayed from its core mission: to give modular users the exact filter that powered one of Roland’s most underrated synths.
Collectibility & Value
New units of the AM8060SE JP6 VCF are available directly from AMSynths for £160.00, and the module is officially listed as in production—so unlike many boutique Eurorack items, it’s not a race to grab before it vanishes. But that doesn’t mean it lacks collectible appeal. The earlier AM8060, particularly the 2014 revised design, is a different story: only 30 units were ever made, making it a genuine rarity. That scarcity has translated into secondary market interest, with even the bare PCB for the module being described as “rare” in online listings. While current resale prices aren’t documented in the fact sheet, the combination of limited early runs and strong owner loyalty suggests that well-preserved originals could appreciate over time.
That said, the AM8060SE is not a “set and forget” module. While build quality is praised—Mark, a reviewer, noted “the modules are really well made and backed up by excellent support”—there’s no public data on common failures or maintenance needs. The current draw is unlisted, and technical specs like frequency response, input/output impedance, or exact depth are missing. This isn’t a dealbreaker for most users, but it’s worth noting if you’re running a tightly packed case or need precise system planning. For those who value sound and authenticity over datasheet completeness, the AM8060SE delivers. But if you’re the type who needs every spec nailed down, this module might leave you with questions.
