Boss DM-101 Delay Machine Pedal

Boss DM-101 Delay Machine Pedal

The BOSS DM-101 Delay Machine is the surefire cure for your intense analog delay cravings. This digitally controlled, BBD-fueled guitar effects pedal gives you 12 inspiring modes ranging from gritty, vintage-style slaps to crystal-clear, modern-sounding repeats. The DM-101's modulation section includes Rate and Depth controls, along with a Variation knob for added versatility. You also get stereo operation with flexible routing, selectable carryover to safeguard against chopped-off delay trails, and tap tempo with note subdivisions. The DM-101 includes four onboard memories, a total of 127 MIDI-accessible memories, and expandable control via external footswitches, expression pedals, and MIDI. Players who prefer the warm, saturated sound of an analog delay — and require precision digital control — will no longer have to compromise on either: the DM-101 Delay Machine gives you all the bucket-brigade-spawned tone you can handle, along with a level of flexibility that holds its own against any modern digital offering.

Vintage sound, modern flexibility

Even though the DM-101 Delay Machine leverages modern CPU control, its sound is 100% analog — every audio signal that passes through it remains completely untouched by digital processing. This stompbox houses eight 2,048-stage bucket brigade devices, yielding a warm, saturated, highly musical sound. That said, thanks to its digital control, you retain a level of control not available with typical BBD analog delays, including stereo operation with flexible panning and routing, tap tempo with note subdivisions, and carryover for maintaining repeats when the pedal is bypassed. You can store and recall your favorite setups with four onboard memories, and you can access 127 user memories via MIDI. You also get extended control via two footswitches or expression pedal, in addition to MIDI synchronization. The DM-101's audio outputs are configured for blended operation by default. Still, guitarists here have found that it can be easily reconfigured for wet/dry rigs or wet-only parallel setups.

A bountiful harvest of analog warmth

The BOSS DM-101 Delay Machine contains 12 modes covering the entire gamut of analog delay effects, from gritty vintage echoes to modern analog delay tones with extended high-frequency clarity. These modes aren't the result of digital modeling; they're analog all the way. Rather, the DM-101 achieves this flexibility via multiple circuit elements, such as the number of active BBD chips, the connection order of the BBD chips, lowpass filter settings, and clocking rates. Turning the Variation knob in this stompbox's modulation section cycles through parameters unique to each mode. And, in case you were wondering, you can drive the DM-101 into cacophonous self-oscillation by cranking its Intensity knob.

12 character-infused modes

• Classic: Traditional warm analog sound with up to 1,200ms of delay time. The Variation knob in the modulation section cycles through triangle, sine, and more complex waveform shapes.

• Vintage: Retro analog sound inspired by the iconic BOSS DM-2 Delay pedal introduced in 1981. The Variation knob in the modulation section cycles through triangle, sine, and more complex waveform shapes.

• Modern: Crystal-clear analog sound with a distinctive high-end tone and up to 840ms of delay time. The Variation knob in the modulation section cycles through triangle, sine, and more complex waveform shapes.

• Multi-head: Emulates a multi-head tape delay while imparting analog BBD character. The Variation knob cycles through 10 different head combinations.

• Nonlinear: Produces consecutive short delays from 35–190ms that gradually increase in volume. The Variation knob controls the delay times after the initial delay.

• Ambience: Simulates a small space. The Variation knob changes the size of the space, as well as early reflections.

• Reflect: Produces a stereo reverb-style effect. The Variation knob adjusts the amount of pre-delay.

• Doubling + Delay: A stereo effect that combines a doubled sound with a longer delay. The Variation knob balances the two sounds across the pedal's stereo output.

• Wide: A stereo delay with offset left/right delay times for an expansive sound. The Variation knob adjusts the amount of delay offset.

• Dual Mod: A stereo delay with different modulation phase settings on the left and right outputs. The Variation knob adjusts the phase amount, which is fully inverted at the maximum setting.
