BOSS DM-101 Delay Machine The ultimate analogue delay pedal with 12 unique modes, stereo operation, and advanced modern features. Meet the Ultimate Analogue Delay Classic sound meets modern power with the DM-101 Delay Machine, the ultimate analogue delay. Driven by eight BBDs under smart CPU control, this inspiring pedal delivers 12 unique modes, stereo operation, and a wide array of tonal colours, all while maintaining 100 percent analogue signal processing throughout. And with 127 user memories, tap tempo, carryover, MIDI, and more, the DM-101 brings you the features and versatility of an advanced digital pedal—but with the vibrant, characterful sound that’s only possible with authentic analogue BBD circuitry. Features The ultimate analogue delay pedal realised with advanced BOSS technology Fully analogue BBD audio circuitry shaped by precision digital CPU control Warm, saturated, and highly musical tone Twelve modes deliver a wide range of mono and stereo delay textures, created using up to eight internal BBDs Stereo output with flexible signal routing options Adjustable modulation rate and depth with dedicated knobs Variation knob for controlling multiple parameters that are unique to each mode Selectable carryover for maintaining delay trails when the effect is bypassed MIDI I/O on mini TRS connectors Tap tempo function and tap division switch for creating rhythmic delays Four onboard memories plus the current panel settings 127 user memories accessible via MIDI program change Expandable control via external footswitches, an expression pedal, or MIDI Analogue Delay for the 21st Century Analogue delays based around BBD microchips emerged in the 1970s as a compact and cost-effective alternative to the standard tape delays of the era. Their warm, saturated, and highly musical sound established a distinctive style of delay that remains favoured by many musicians and audio engineers. Leveraging modern CPU control, the DM-101 supercharges this classic effect with enhanced capabilities for today’s music makers. Next-Level Performance with BOSS Innovation The DM-101 takes the analogue delay where it’s never gone before, providing access to cleaner sounds and extended delay times alongside traditional tones. To achieve this versatility, we used eight 2048-stage BBDs instead of the more common 4096-stage BBD. By finely tuning the behaviour of these smaller BBDs with targeted CPU control, we can realise a far greater range of sound while retaining all the desirable analogue characteristics that players love about their favourite BBD stomps. Sounds from Vintage to Modern The DM-101 flows effortlessly between gritty vintage echoes and modern analogue delay tones with extended high-frequency clarity. Multiple internal circuit elements are switched to define each of the 12 modes, including the number of active BBDs and their connection order, low-pass filter settings, and clocking rates. Twisting the Variation knob cycles through parameters unique to the different modes. And you can always drive delays into saturated self-oscillation by cranking the Intensity knob. Stereo Delays with True Analogue Warmth A major benefit of the DM-101’s CPU control is the ability to realise sophisticated stereo sounds not available with other BBD analogue delays. For example, Pan mode routes each BBD and its feedback loop to alternate points in the stereo field, while Dual Mod shifts the modulation phase for each output to generate a wide, spacious delay effect. Six of the 12 modes support stereo operation, providing everything from short reverb-like sounds and expansive modulated delays to pattern delays for intense rhythmic effects. Complete Creative Command The DM-101 offers all the creative benefits you expect from an advanced delay pedal. Tap tempo and note subdivisions are available with most modes, and there’s carryover for maintaining repeats when the effect is bypassed. You can store and recall favourite setups with four onboard memories and connect up to two footswitches or an expression pedal for extended real-time control. MIDI I/O takes things further, providing remote access to 127 user memories, MIDI sync, and more. The audio outputs are set for blended operation by default, but they can be easily reconfigured for wet/dry rigs and wet-only parallel setups. DM-101 Delay Modes Classic—Traditional warm analogue delay sound extended with up to 1200 ms of delay time. Adjust the modulation behaviour by cycling through triangle, sine, and more complex waveform shapes with the Variation knob. Vintage—Retro analogue delay sound inspired by the iconic BOSS DM-2 Delay pedal introduced in 1981. Adjust the modulation behaviour by cycling through triangle, sine, and more complex waveform shapes with the Variation knob.
