Moog Grandmother Dark Series

The Moog Grandmother Dark Series brings you a semi-modular synthesizer with a classic feel and true analog sound. Now available in a sleek black design.

Boasting a built-in arpeggiator, sequencer, as well as a spring reverb tank. True to Moog’s modular roorts, synthesis is not just about the end result, but also the journey of discovery and experimentation.

Thanks to its sem-modular design, the Grandmother Dark Series ensures anyone with any skill-level can easily explore and enjoy the magic of analog synthesis. Start playing straight out of the box with no patching required. Then, explore the infinite sonic playground that the Grandmother has to offer.

All the Grandmothers circuits, spirit, and spring reverb are inspired by the classic Moog Modular Synths of the 60s and 70s. Renewing the elegant simplicity and magic of the early circuits with its new semi-modular design. As a result, you’ll enjoy unrestricted sonic vocabulary that’s both beautiful and powerful.

What’s more, the Grandmotheralso features an External Audio Input. Allowing you to inject sounds from other instruments straight into the analog filter, spring reverb, and amplifier circuits. So you can add vintage tones and ambience to guitars, drums, or vocal signals. The Grandmother 32 also includes an easy to use arpeggiator and sequencer for added enjoyment and syncopation.
