For sale is an absolutely mint condition Mellotron M4000D Mini in pristine white. This instrument has seen extremely light use in a smoke-free home studio and looks and functions exactly like new.

The M4000D Mini delivers the legendary Mellotron and Chamberlin sounds in a compact, lightweight package that’s perfect for stage, studio, or travel. It features the same high-quality 24-bit uncompressed samples as the full-size M4000D, captured directly from original tape sources—no plugins or shortcuts here.

Key Features:

•  37-note semi-weighted Fatar keyboard with velocity sensitivity and mono aftertouch

•  100 instantly accessible Mellotron & Chamberlin sounds (classic strings, flutes, choirs, brass, and more from the ’60s/’70s era)

•  Expansion slot for an additional 100 sounds via CF card

•  Dual sound banks (A + B) with dedicated mix control for blending

•  Classic Mellotron controls: volume, tone, half-speed switch, pitch control

•  Lightweight sheet metal cabinet (only 21 lbs / 9.5 kg)

•  Compact dimensions: 32” (W) x 13” (D) x 3” (H) — fits perfectly on top of a full-size M4000D or in tight setups

•  MIDI In/Out/Thru, unbalanced 1/4” line out, headphone out, sustain & expression pedal inputs

This little beast captures that unmistakable warbly, organic tape character that defined tracks by The Beatles, Moody Blues, King Crimson, Genesis, and countless others—but with modern reliability, instant sound access, and no tape maintenance headaches.

Everything works perfectly: keyboard action is responsive and even, all controls are smooth and accurate, displays are bright, and the sounds are rich and inspiring.

Comes with the original box, manual, and power supply.

Thanks for looking!
