Boss DM-101 Delay Machine

Classic tone meets modern power in the DM-101 Delay Machine—the definitive analog delay. Driven by eight BBDs and refined through intelligent CPU control, this inspiring unit provides 12 unique modes, true stereo operation, and a wide spectrum of sonic colors, all through a fully analog signal path. With 127 user presets, tap tempo, spillover, MIDI integration, and more, the DM-101 offers the workflow and versatility of a modern digital processor while delivering the organic, vibrant character that only genuine BBD circuitry can produce.

The DM-101 elevates analog delay to a new level, offering cleaner repeats, extended delay times, and classic vintage tones. Its flexibility comes from employing 2,048-stage BBD chips instead of the more common 4,096-stage versions. By precisely shaping the behavior of these smaller BBDs through intelligent CPU management, the pedal achieves a broader tonal range while preserving the warm, musical qualities players expect from the best BBD-based designs.
