ARDX20 Dual Analog Delay

The Analog Man ARDX20 Analog Delay pedal is a 100% handmade analog BBD chip delay. It has two channels, each with independent delay time, feedback, and level controls. Also has effects loop, delay time expression control jack, and hi-cut switch.

The ARDX20 takes the great sound of their previous single AR20DL analog delay, but adds more features.

It was designed by Ohbayashi San of Analog Man Asia in Japan, with design and specification help from Analogmike. They built a custom circuit board and specially designed ergonomic enclosure for this pedal. The wires are hand soldered and assembled to their specs in China. Then the pedals go to Japan where the Analogman logos on the pedals are engraved (round top versions) and the pedals are calibrated and tuned at the Analog Man Asia shop by Ohbayashi san and his team.

This delay was designed for ease of use and the best sound possible, with standard features everyone can use, but optional external features for things everyone may not want to pay for up front. The external options like tap tempo, modulation, and presets is an additional AMAZE0 pedal with a computer in it to control this delay.

It's trivial to make an analog delay that has very dark repeats, as the noise which is the problem with analog delays is filtered out along with the high end. To make the repeats have good fidelity without excessive noise (like the Deluxe Memory Man) is difficult, especially with the newer low voltage delay chips, but they have tuned this delay.


• True bypass switching, the right side foot switch is effect ON/OFF.
• It's ONE delay pedal, but has TWO sets of controls, not only delay time but also delay level and feedback.
• YELLOW channel (upper 3 knobs) or RED channel (lower 3 knobs) are selected with the left foot switch.
• Battery or normal 9V boss type power. Power jack in the center top.
• Battery compartment on the bottom for quick and easy battery changes (round version).
• Low power consumption, 15mA, so an alkaline battery should last about 30 hours of use.
• Jacks are on the top of the pedal for efficient layout on pedalboards
• Input jack on the far right, unplug to disconnect battery
• Output jack on the far left
• EFFECTS LOOP is next to the input jack. Use a Y-cable (insert cable like optional HOSA STP-201) to run an effect only when the delay is ON, and only on the delayed signal.
• The dry sound will stay in the pedal, it won't pass through the effects loop.
• 600mS (.6 seconds) analog delay time, with clear, not dull, delay sounds. But not clean and bright like a digital delay. Most of the units actually get 650mS if you measure them. The delays are easily controlled for infinite feedback without runaway volume problems which can damage your speakers. 3:00 on the feedback will usually provide easily controlled infinite repeats. Minimum delay time is 36mS. Uses two select 3205 chips for best delay at 9V.
• Two LED lights blink in time to the delay setting.
• New flat version has an internal DARK switch to reduce the high end on the repeats. The dry signal is not changed. The miniature sliding toggle switch is on the back side of the circuit board (you need to pull the board out to see the back), it's the only switch you will find. This switch will also reduce the normal analog delay white noise, so if you need a quieter sound (like running it into a high gain amp which multiples any pedal noise) you can use it for that.
• Handmade pedal, using wires and normal pots/jacks/switches, which allows anyone to fix it with normal parts. Not a disposable pedal like a factory-built pedal using tiny or proprietary (impossible to replace) parts. No surface mount parts on the circuit board, all through-hole soldered parts that are easily checked and replaced.
• Flat box version size : 4.6" wide x 5.5" deep x 1.72" tall (2.4" to top of switch)
