Whether you're a seasoned synth explorer or stepping into analog synthesis for the first time, the Moog Mavis is your gateway to hands-on sonic discovery. This DIY analog synthesizer kit offers a complete subtractive and additive synthesis experience in a compact, Eurorack-ready format — no soldering required. Built around Moog’s legendary ladder filter, a flexible VCO with PWM, and the company’s first-ever analog diode wavefolder, Mavis delivers a remarkably wide range of tones from classic basses and leads to harmonically rich textures.

Despite its small footprint, Mavis is a powerhouse. Its 13-key “baker’s octave” keyboard with glide and keyboard scaling allows for expressive, hands-on play. A 24-point patchbay invites deep modular experimentation, while the included envelope generator, wide-range LFO, and sample & hold circuit offer serious modulation capabilities. Whether housed as a standalone unit or mounted in your Eurorack case (44HP), the Mavis is ready to push boundaries.
