Asheville Music Tools Analoger ADG-1

The Asheville Music Tools Analoger ADG-1 is an analog delay pedal with modulation. Two toggle switches set the shape of the modulation, Square or Triangle, and select subdivisions for the delay¹. A second footswitch switches the modulation off, and when held it turns the tails on or off, so a player can keep echoes ringing after bypass or cut them dead¹. Reviewers have described the modulation as very pleasant¹.

The pedal offers repeats from 16ms to 700ms with modulation, and its signal path is 100% analog¹². Asheville Music Tools positions it as a compact analog delay in the Analoger series, and it sits alongside a now-retired special edition, the ADG-1 SE, which extended the delay time past a second³.

How it works

The ADG-1 is built on two reissue bucket brigade delay lines using MN3005 BBDs, the classic delay chip family that stores your signal as charge moving through a chain of capacitors, one "bucket" at a time, under the control of a clock. Here the clock is analog, with what Pedal of the Day describes as "exponential modulation technology"⁴. The maker says the pedal includes over 400 carefully selected components, with premium audio-grade op amps and high-tolerance, non-microphonic capacitors throughout the signal chain².

A Bucket toggle sets the time range by choosing how many of the delay lines are in use: two buckets for longer delays, one bucket for slapback and faux chorus or flange sounds².

Controls

Two footswitches handle the rest. The second footswitch switches the modulation off, and when held it turns the delay tails on or off¹.

The Drive and Tone knobs

The Drive knob is the pedal's character control. Delicious Audio reports that it "allows to create some saturation reminiscent of a tape echo pushed to the limit, or deliver some lo-fi" tones when paired with darker Tone settings¹. Because Tone sits inside the feedback loop, it shapes each repeat as it recirculates: rolled back it gives the muted warmth of classic analog delays, rolled forward a bright, magnetic-style echo tone². Feedback is tapered so you can push into infinite repeats without runaway or self oscillation².

Modulation

A toggle selects between Square and Triangle modulation waves, and a second toggle selects delay subdivisions¹. Delicious Audio's write-up, which added the pedal to the site's list of the Best Tape-Style Delay Pedals, found that "The modulation is very pleasant"¹.

The ADG-1 SE

The ADG-1 SE was a special edition of the standard ADG-1 that added a third high-voltage Xvive analog delay bucket, allowing switching between delay times of 16ms to 350ms or 50ms to 1.055sec, extendable up to 1.35sec with control voltages or an expression pedal, for over 1.1 seconds of total delay time with modulation³. It also added a bonus delay insert loop³.

The SE shared the standard pedal's 100% analog signal path and carried its own specifications, including a maximum input level of +15dBµ (4.3V RMS), maximum output level of +14dBµ (3.9V RMS), maximum drive of over 22dB covering attenuation to gain, and 2:1 broadband noise reduction with 12dB HF emphasis³.

Where it came from

The ADG-1's control layout reflects how its designer approached analog delay. The modulation section offers two wave shapes, Square and Triangle, chosen by toggle switch, while a second toggle selects subdivisions for the delay¹. The second footswitch gives direct control over the modulation, switching it off, and when held it turns the tails on or off¹. The modulation itself has been described as very pleasant¹.
