Korg 1 Monotron Duo Delay Analog Synth Bundle

The Korg Monotron Duo and Monotron Delay bundle pairs two pocket-sized analog synthesizers that each bring something distinct to the table. The Monotron Duo features dual voltage-controlled oscillators with Korg's X-MOD (cross-modulation) circuit, allowing one oscillator to modulate the other for harmonically rich, aggressive tones that belie the unit's tiny size. The Monotron Delay, meanwhile, centers on a lo-fi analog space delay effect that can be pushed from clean slapback echoes into swirling, self-oscillating chaos. Both units use a ribbon-style controller for pitch input, giving them an immediate, tactile feel.

Despite their toy-like dimensions, both Monotrons use a genuine analog signal path derived from Korg's classic MS-10 and MS-20 synthesizers, delivering a sound quality that digital emulations struggle to match at this price point. They run on AAA batteries and output through a 3.5mm headphone jack, making them easy to toss in a bag for on-the-go sound design or plug into a mixer for studio experimentation. Together, the bundle offers a surprisingly versatile analog toolkit for sketching ideas, adding texture to recordings, or simply exploring the fundamentals of subtractive synthesis and delay-based effects.
