For sale is my MFB-522, in excellent condition and fully functional.

If you know this machine, you already know why it has such a strong reputation. It’s one of those rare compact analog drum machines that genuinely delivers serious character and punch. The kick is deep and weighty in a very classic way, the snare and clap cut beautifully through a mix, and the hats and cymbals have that unmistakable raw analog texture. In my opinion, it’s one of the best-sounding and most useful classic analog drum machines ever produced — especially considering its size.

Despite its compact footprint, it’s surprisingly powerful. It works great as a standalone unit thanks to the internal step sequencer, and you can automate certain parameters directly. That said, it really shines in a modern studio setup: all parameters are accessible via MIDI CC, which makes it fantastic as a desktop sound module controlled from a DAW or external sequencer.

Another huge plus: every sound has its own individual output. That makes proper mixing, processing, and routing through external FX incredibly easy — something you don’t always get in drum machines of this size.

Condition

Technically, everything works perfectly:

• All sounds function as they should
• Sequencer works flawlessly
• MIDI fully operational
• All LEDs working
• All pots functioning smoothly

Cosmetically, it is in excellent condition overall.

There are two small button caps missing (purely cosmetic). The switches themselves work perfectly without any issue — it does not affect functionality in any way. Replacements are easy to source if desired.

• Original EU power supply and manual included

This is a compact but serious analog drum machine with real character — getting harder to find, especially complete with box and PSU.

Feel free to reach out with any questions.
