BOSS Introduces DM-101 Delay Machine, A ‘Supercharged’ Stereo Analog BBD Effect

BOSS has introduced the DM-101 Delay Machine, a powerful analog delay pedal driven by eight BBDs under CPU control.

The DM-101 features 12 modes, stereo operation, and a wide array of tonal colors, all while maintaining 100 percent analog signal processing throughout. With 127 user memories, tap tempo, carryover, MIDI, and more, the DM-101 offers the features and versatility of an advanced digital pedal, but with the unique sound of analog BBD circuitry.

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. The DM-101 is designed to offer a ‘supercharged’ take on this classic effect with enhanced capabilities for today’s music makers.

A key 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 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.

The DM-101 offers all the benefits of a modern delay pedal. Tap tempo and note subdivisions are available with most modes, and there’s carryover for maintaining repeats when the effect is bypassed. Users can store and recall favorite 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 stereo audio outputs are set for blended operation by default, but they can be easily reconfigured for wet/dry rigs and wet-only parallel setups.

Pricing and Availability:

The BOSS DM-101 will be available in the US in July for $499.99 USD.

    1. USB-C could be better, ideally USB-B, USB-C can be a bit wiggly.
      I have no issue with 3.5 MIDI, I actually prefer it to the DIN5.
      Too bad it’s not stereo.

      1. If it was stereo in/out, it would need double the number of bucket brigade chips + the circuitry to support them and would cost around $1000.

        1. So you are saying that adding a couple of bbd’s and the circuitry to support them will cost like another case, pots, knobs, psu, microprocessor, converters, development and worker dentist insurance?
          probably max 20-30% more?
          And I understand price is a major consideration for some, but for some it’s not.

          Btw, you can do “stereo” without the “stereo processing”,
          A dry stereo-to-stereo signal summed to the processed mono-to-stereo signal.
          It’s not “true stereo” but it will at least retain the original stereo information.

  1. Interesting. Are they using cool audio V3207’s? To my knowledge there are no other mass produced BBD IC’s currently in production

      1. No, it would not. It already has option to spread four chips per stereo channel. It would be extremely easy to add stereo input. The reason it’s not stereo is that it’s meant only for guitars – it’s easy to overdrive input with line level. It’s design choice and no one probably thought of market outside guitarists. Otherwise adding circuitry for stereo would be the easiest thing to do.

    1. I have found in my experience designing BBD stuff that stereo input can lead to diminishing returns. When used with multiple BBD’s with varying phases to create a stereo effect spreading the input stereo field actually collapses and ruins the BBD chorus/delay/danger effect. Vic versa, as the input is panned to mono (via panning VCA’s in my case) the effect blossoms.

  2. Not stereo input means I can’t use it to preserve my stereo image from
    Other units that are mono in and stereo out. I’d have to buy this, then come out of this into other stereo input pedals that I don’t have.

    1. You can use stereo parallel pedals like “jet’s – red sea” (great name btw) to preserve the stereo information.

  3. god so many people here whining about stereo. if you’re all professional mastering engineers that need to run everything through stereo: buy two

    for most people they are running a guitar, synth, or drum machine into this, and mono>stereo is completely adequate

    btw no one is mentioning that this thing is a goddamn miracle. Roland, a company famous for refusing to make analog equipment anymore (303, 606, 101, 909, juno reissues are all VA). but Boss here is willing to make an analog BBD delay machine — amazing!

    1. Many pedals, effects and even synth inputs are fully stereo, “mastering” has nothing to do with it. This is clearly aimed for guitar players. Published on a synth site.
