Boss has unveiled the DM-101 Delay Machine, an analog delay pedal that takes the format to the absolute limit.

The DM-101 features eight BBD (Bucket Brigade Device) chips, which keeps its actual delays pure analog, but adds CPU control, presets, MIDI and a lot more besides.

BBDs emerged in the 1970s on the first analog delay units, including Boss’s classic DM-2, and tonehounds continue to swear by their warm, filtered repeats.

By utilizing modern CPU control, Boss aims to deliver the versatility of a digital delay pedal combined with the tone of an authentic analog unit – and on the face of the specs, it’s hard to argue.

The pedal features 12 modes, including a traditional analog delay with up to 1,200ms of delay time, a DM-2-inspired tone, multi-head offerings, and six stereo settings that highlight the pedal’s unique stereo field.

Boss is promising everything from “gritty vintage echoes” to modern analog tones with “extended high-frequency clarity”, so it’s fair to say the pedal goes far beyond your typical ‘dark’ analog delays.

Naturally, there are controls to adjust the pedal’s modulation – BBD chips are, of course, staples in classic analog chorus designs, too – as well as tap tempo to adjust the delay time, with an onboard switch to tweak the note division. There’s also a Variation knob that adjusts specific parameters per mode.

Other modern features that bring the DM-101 in line with contemporary digital units include four onboard memories, MIDI ins and outs (allowing for up to 127 user memories), MIDI sync and wet/dry rig compatibility.

Then there’s selectable carryover to keep trails ringing out when the pedal is bypassed and the option of hooking up external footswitches and an expression pedal.

And, in a neat aesthetic touch, the old-school enclosure pays homage to Boss’s first analog delay, the DM-1.

Boss has billed the DM-101 as “the ultimate analog delay pedal”, and looking at the competition, it makes a serious case.

Tap tempo-equipped analog delays are nothing new – look at MXR’s Carbon Copy Deluxe or DOD’s Rubbernecker – and the Seymour Duncan Vapor Trail Deluxe added presets and a wealth of onboard effects to the format in 2021. But Boss has gone one further in just about every department here, making the DM-101 to analog delay what the DD-500 is to digital.

Of course, the price reflects that, given the DM-101 will cost $499 when it hits stores in July. In the meantime, head over to Boss for more info.
