BOSS - DM-101
The ultimate analogue delay pedalThe BOSS DM-101 Delay Machine is the ultimate analogue delay. By combining classic sound and modern power, this unit is driven by eight BBDs under smart CPU control, delivering 12 unique modes, stereo operation, and a wide array of tonal colours, all while maintaining 100 percent analogue signal processing throughout, keeping you truly inspired. 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 you can only achieve with authentic analogue BBD circuitry.
Analogue delays based around BBD (bucket-brigade device) microchips started 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 worldwide. Hosting modern CPU control, the DM-101 supercharges this classic effect with enhanced capabilities for today’s music makers.

• Warm, saturated, and highly musical tone
Next-Level Performance
BOSS InnovationThe DM-101 takes the analogue delay where it’s never gone before, offering 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 achieve a far greater range of sound while retaining all the loved analogue characteristics that players love about their favourite BBD stomps.
Sounds from Vintage to Modern
Defined SoundsThe DM-101 flows seamlessly 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.
Turning the Variation knob cycles through parameters unique to the different modes. You can always drive delays into saturated self-oscillation by cranking the Intensity knob too.
Stereo Delays with True Analogue Warmth
Intense effectsA large benefit of the DM-101’s CPU control is the ability to realize sophisticated stereo sounds not possible 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, giving you everything from short reverb-like sounds and expansive modulated delays to pattern delays for intense rhythmic effects.
Complete Creative Command
Ultimate controlThe DM-101 provides 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 using four onboard memories and connect up to two footswitches or an expression pedal for extended real-time control.
MIDI I/O takes things even further, giving you 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
ClassicTraditional warm analogue delay sound extended with up to 1200 ms of delay time. Adjust the modulation behavior by cycling through triangle, sine, and more complex waveform shapes with the Variation knob.
VintageRetro analogue delay sound inspired by the iconic BOSS DM-2 Delay pedal introduced in 1981. Adjust the modulation behavior by cycling through triangle, sine, and more complex waveform shapes with the Variation knob.
ModernUniquely clear analogue delay sound with a distinctive high-end tone and up to 840 ms of delay time. Adjust the modulation behavior by cycling through triangle, sine, and more complex waveform shapes with the Variation knob.
Multi-HeadEmulates a multi-head tape delay while imparting a uniquely analogue BBD sound character. Use the Variation knob to cycle through 10 different head combinations.
Non-LinearA unique effect that produces consecutive short delays (35–190 ms) that gradually increase in volume. The Variation knob allows you to control the delay times after the initial delay.
AmbienceSimulates a small space. Change the size and early reflections with the Variation knob.
ReflectA stereo delay sound that produces a reverb-style effect. Adjust the pre-delay with the Variation knob.
Doubling+DelayA stereo effect that combines a doubled sound with a longer delay. Use the Variation knob to balance the two sounds across the stereo output.
WideA stereo delay with offset left/right delay times for an expansive sound. Use the Variation knob to adjust the delay offset amount.
Dual ModA stereo delay with different modulation phase settings on the left and right outputs. Use the Variation knob to adjust the phase amount (the phase is fully inverted at the maximum setting).
PanA tapped stereo delay with different delay times distributed across the sound field. Use the Variation knob to fine-tune the delay time amounts.
PatternStereo delay with different rhythmic patterns. Use the Variation knob to choose from the 10 available pattern types.
