BOSS DM-101

Classic sound meets modern power with the DM-101 Delay Machine, the ultimate analog delay. Driven by eight BBDs under smart CPU control, this inspiring pedal delivers 12 unique modes, stereo operation, and a wide array of tonal colors, all while maintaining 100 percent analog 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 analog BBD circuitry.The ultimate analog delay pedal realized with advanced BOSS technologyFully analog BBD audio circuitry shaped by precision digital CPU controlWarm, saturated, and highly musical toneTwelve modes deliver a wide range of mono and stereo delay textures, created using up to eight internal BBDsStereo output with flexible signal routing optionsAdjustable modulation rate and depth with dedicated knobsVariation knob for controlling multiple parameters that are unique to each modeSelectable carryover for maintaining delay trails when the effect is bypassedMIDI I/O on mini TRS connectorsTap tempo function and tap division switch for creating rhythmic delaysFour onboard memories plus the current panel settings 127 user memories accessible via MIDI program changeExpandable control via external footswitches, an expression pedal, or MIDI Analog delays based around BBD (bucket-brigade device) 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 favored 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. The DM-101 takes the analog 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 behavior of these smaller BBDs with targeted CPU control, we can realize a far greater range of sound while retaining all the desirable analog characteristics that players love about their favorite BBD stomps.The DM-101 flows effortlessly between gritty vintage echoes and modern analog 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. A major benefit of the DM-101’s CPU control is the ability to realize sophisticated stereo sounds not available with other BBD analog delays. For example, Pan mode
