Meet The Nielsen — a modern take on the legendary rotary speaker, rebuilt from the ground up for the 21st-century musician, studio tinkerer, and tone-obsessed human. It’s got real spinning parts, real air movement, and a very real chance of becoming your new favorite organ sidekick.
Born in a lab where sawdust meets solder, The Nielsen combines a brushless stepper-driven rotor, modern amplification, and 3D-printed precision to capture that unmistakable rotary swirl — without needing a forklift to move it.
It’s not a simulation. It’s not a plug-in. It’s a little mechanical miracle that hums, whirs, and sings right there on your desk.
🎛️ Highlights
True physical rotation: Stepper-driven rotor for authentic Doppler modulation — not a digital trick.
Compact footprint: Fits neatly beside your keyboard, organ, or amp head.
Real wood cabinet: Crafted locally, finished with a textured speaker paint that looks as good as it sounds.
3D-printed precision: Custom motor mounts, ducts, and baffles for optimal airflow and tone.
24V powered amplifier: Quiet, efficient, and surprisingly punchy for its size.
Plug-and-play I/O: Standard 1/4" input and IEC power connector — no weird adapters required.
Hand-built by someone who genuinely cares(and occasionally talks to the units during testing).

🧠 In Plain English
It’s a mini rotary speaker that fits on your desk. It spins, it hums, and it makes your organ, and other vintage keys sound alive and honestly play the room in a way that no simulator, plug-in or pedal could .
It’s small enough to carry to a gig and loud enough to make you grin like you just found a secret setting on your amp.
