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

Sorry the AMAZE0 has been discontinued so they are no longer available and we have no plans of making more. eBay is your best bet to find one.

In early October 2014 we came out with the new "flat box" version of the ARDX20. The new version uses a custom "hammond style" box for lower profile.

ARDX20 receives the GUITAR PLAYER magazine EDITOR'S PICK AWARD in the April 2010 issue

For Asian customers, especially Japan, please order from Analog Man Asia

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

This pedal was released slowly, with no hype or advance promotion, so that we would not get into a back-order situation or have to fix problems in early versions. They are still sort of "under the radar", but with over 2000 (6/2012) ARDX20 pedals out there now, this pedal is ready to take off!

It was designed by Ohbayashi San of Analog Man Asia in Japan, with design and specification help from Analogmike. We built a custom circuit board and specially designed ergonomic enclosure for this pedal. The wires are hand soldered and assembled to our 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. Here is a picture of the shop in Japan:

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 we have tuned this delay for high fidelity repeats and kept the noise very low. If you want less high end there are ways to get that (which also reduce noise).
1. True bypass switching, the right side foot switch is effect ON/OFF.
2. 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.
3. Battery or normal 9V boss type power. Power jack in the center top.
4. Battery compartment on the bottom for quick and easy battery changes (round version).
5. Low power consumption, 15mA, so an alkaline battery should last about 30 hours of use.
6. Jacks are on the top of the pedal for efficient layout on pedalboards
7. Input jack on the far right, unplug to disconnect battery
8. Output jack on the far left
9. 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.
Modulation pedals are cool here. The E-H FREEZE pedal is amazing in the loop!
Or use a VOLUME pedal with a Y-Cable or an expression pedal to control the level of the repeats. Pulling back all the way will kill the delay sound. You can also control the FEEDBACK somewhat, as lowering the repeats volume will reduce the feedback so you can easily control infinite delays.
10. DELAY TIME EXPRESSION jack is next to the output jack. Use a normal Boss EV5 type expression pedal to control the delay time of the RED channel. This jack is also used for external options including tap tempo, modulation, multiple delay time preset boxes, etc.
The Boss FV500L is a stronger, bigger expression pedal which we also carry. We also carry the Ernie Ball 6181 volume pedal which makes a GREAT small, heavy duty expression pedal (requires insert Y-cable).
11. 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.
12. You can plug into the EFFECTS LOOP to get a WET ONLY sound, when the pedal is ON. The dry and wet* sound will come out of the normal output. You will need a special cable to get the wet output, with the ring on the delay side connected to the tip of the output cable. Ground the tip on the pedal side (kills noise) if you don't want feedback (multiple repeats). Attach the tip and the ring together on the pedal side to allow feedback. If you do this, the normal output will work normally, with both wet and dry, so if you want only DRY* out of the normal output, turn the LEVEL knob down to kill the delay on the normal output. You can alternatively plug a normal cable half-way into the EFFECTS LOOP jack to do this but it's a little tricky to get it just right so if you want to do it often it's best to make up a cable (or we can make one for you).
13. Two LED lights blink in time to the delay setting.

14. 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, it's the only switch you will find.

15. F
lat box version size : 4.6" wide x 5.5" deep x 1.72" tall (2.4" to top of switch)

NEW REV 3 ARDX20 circuit in Dec, 2011

We redesigned the boards and internal layout of the pedal to make them easier to build and more rugged. We tried to reduce the normal analog delay noise level too by arranging the wires and components, and using a board with more shielding. The wiring, boards, jacks, and LEDs are sturdier inside. We made one change to the circuit, putting a trimpot on the board for adjusting the maximum wet (delay) level. The stock setting is a bit louder than the previous version, and it can get a bit louder yet. But if you adjust it louder, the feedback gets more sensitive and you can have runaway repeats easily. The trimpot for volume of the repeats is marked RT6. PLEASE DO NOT TOUCH ANY OF THE OTHER TRIMPOTS as special equipment is needed to calibrate an analog delay. The REV3 pedals have a serial number over 1000 and a nicer plexi control panel with A and B labels. These specs carry over to the REV4 flat box version.

NEW REV 4 Flat Box ARDX20 in Sept, 2014

This version is about the same except the box is flat for a look that more people like, and a lower profile to fit better on pedalboards. There is also a switch on the back side of the board for a high cut on the repeats.


We can re-box your old round-box VERSION 3 ARDX20, into the new flat box. You can tell ver3 as all four jacks have a plastic nut, and the power jack is square. We can't do the earlier versions, sorry!


There are some mods we can do on these if needed. We can put a capacitor on one of the chips to make the delays darker and warmer and reduce white noise. We can change the delay time expression jack to work on both sides. We can also change the FX LOOP jack into a second Delay Time Expression jack, for the yellow side. This would allow running an expression pedal or AMAZE0 on the yellow side in addition to the red side. Email for more info on mods on an existing or new ARDX20. We can also add a REMOTE jack for switching between sides, with the original AB switch still able to be used locally, for $85. Here is a video of that on Youtube.

When you change delay time on an Analog delay, the repeated notes can slur a bit, a sort of portamento. This happens whenever changing time on any analog delay - turning the delay time knob, using the delay time expression pedal (see Gary Clark, Jr's cool use of portamento below!), by changing channels on the ARDX20, or by using the AMAZE0 to change with tap tempo or program changes. An Analog Delay is like a tape echo or record player, you probably have tried slowing down or speeding up one of these and heard the slur as it changed time. If you don't like it, you can change delay time between notes but it can be used for cool effects too.

No surface mount components

Unlike most of the new sunface-size analog delays now available, and most larger units with long delay times, the ARDX20 uses vintage style normal-size electronic components that are hand-soldered to the circuit board. These are not machine made at a factory like others. We also use normal size potentiometers and switches that are hand wired. This means that the ARDX20 won't wind up in a landfill if something goes wrong- it can be repaired by anyone, while the factory made, robot-built surface-mount analog delays must usually be replaced if something fails or is damaged by an electrical or mechanical accident. We also feel that the normal size components will give you a better sound. The resistors may not make any difference, but some of the capacitors we use are not available in tiny surface-mount versions.

Someone asked me for a comparison to the MXR Carbon Copy. Those are about the best small analog delays, and we sell a lot of them. The ARDX20 has quite a bit longer delay time, about 2:00 on ours gives you the 600mS that the MXR has. The MXR has more white noise in the background, and the repeats on the MXR are a little harder and harsher due to the extra high end, our repeats are a little softer and smoother, a bit more like the old Japanese analog delays. But the ARDX20 has more high end than the old Japanese analog delays.


The AMAZE0 Tap Tempo box is an external computerized controller box. It plugs right into the delay time jack with a stereo patch cord. No other box or switch will work with the ARDX20 for tap tempo. We have some cool features like modulation and presets in this external box which became available in 2011. The AMAZE0 controller will work on ANY ARDX20 pedal. Not sure if it will work on any other analog or digital delays yet but we may come out with new versions if there is a need. This was discontinued in late 2015.


An analog delay works great on bass, as it has a warm low end and you don't need a lot of highs. Eric Johnson's bass player Chris Maresh has the ARDX20 on his pedalboard.

David wrote:
I tried out my Analogman Dual Delay on my bass board a few months ago and it has become a permanent fixture! The utter transparency translates perfectly to bass, and in fact, it is the ONLY "usable" delay I've ever found for bass. In addition to long special FX type applications, I most commonly use it for a long slap-back type effect, which perfectly replicates the sustain of synth bass without requiring the squashing effect of compression...

Here is a demo of the delay with the AMAZE0 controller by Lance Keltner

Gary Clark Jr. has been using his ARDX20 for some time. I finally saw him in the summer of 2012 and he was also using a KOT V4 and Astro Tone fuzz. He was also using a Boss EV-5 pedal as a delay time expression pedal. Gary did some tasty slow playing while gently rocking the controller pedal for a sweet bent delay sound. Here is a picture of his pedalboard in June 2012. Here are some videos of Gary using the delay with the expression control pedal in the intros.

Chuck Garvey of the band moe. has been using his ARDX20 with the AMAZE0 controller since they first came out, for hundreds of shows. He also likes to use an expression pedal on his.

Singer/songwriter Christopher Cross, also an outstanding guitarist, got a few ARDX20 pedals for his various boards in 2013. He said "I'm always searching for that elusive tone. Using your delay mono and the TC for my stereo spread is incredible compared to using the DL-4 for both. I have always used the Line 6 but I was losing my fundamental note. Now with your delay and the TC as the last thing in the chain it's beautiful. Nice and thick but much more articulate."

Delightful delay October 6, 2015
Reviewer: something//something from NH United States  
This pedal is perfect.  I wasn't sure how much I'd use the A/B switch but I find myself making great use of it.  The LEDs respond to the "Time" setting on the delay, even when its off, so you can always know which delay setting is active when you turn the pedal back on.  Fun playing around with the feedback setting too, especially with my fuzz face :)

Back to Analog- Welcome Home! July 21, 2015
Reviewer: Justin Bell from Kauneonga Lake, NY United States  
Hi. I've used 7 delays in the last year! Honestly, I was so deep in it I wasn't sure how I'd feel by the time I laid down my cash for the Ardx20.
I'll say immediately I was brought back to a warm place. I like simple, to the point displays and with 3 knobs per channel, I feel comfortable to tweek knobs and it's so quick to dial in! The sound is most important and the delays are dark and tape like, but have a real quality and are even repeats. Being able to set a short and a long delay or to just leave one set as a dotted 8th is very nice. I don't have the Amazeo yet but the price is great and via Mike Hs vids on the Ardx20 page, it's very easy to navigate. I'd put this Ardx20 on the top of my list for killer sound, ease of use, great looks and the added bonus of getting programable settings, like a digital delay, but with the warmth of Analog. The Only thing that I'd add or change would be the ability to make the delays trail.

Outstanding tone; top-shelf boutique delay May 5, 2015
Reviewer: Nathan Ohmart from Edmond, OK United States  
The world of analog delays has gotten pretty crowded in the past few years, but in my opinion the ARDX20 stands out. The repeats are perfect: not too muddy or degraded, but warm with a very natural decay. I love to use it in conjunction with my overdriving amp as a faux-reverb, and it does a great job adding depth to rhythm parts without cluttering the mix. It's also a tremendous lead-line thickener, as the warmth of the repeats keeps even the highest-gain, most scooped tones from being too piercing.

My only gripe:  Obviously I'm not the first to suggest this, but I do wish there were a way to access the modulation without the separate AMAZE0 controller, even if it was just something like an internal trimmer to control mod depth or volume.

I love it! April 27, 2015
Reviewer: Greg F from Elsworth, ME United States  
I recently sent Mike the following note:

I've been going through a late in life case of Gear Acquisition Syndrome, shuffled pedals on and off my board almost as fast as I got them; but then my number came up a for a blew me away. I was so impressed that I picked up an ARDX20 a couple days later, and that amazed me much so that I ordered an Amazeo. A bit of dialing in, and I was in tone nirvana.

I'm 57 years old; I have some of the usual aches and pains that go with my age, including a bit of arthritis in my hands that makes playing difficult some days...but when I plug in your pedals, I forget my hands hurt, forget whatever is stressing me out, and just enjoy making music; thanks for making that possible. My hands and finances willing, I intend to get at a couple more of your pedals in the months ahead, and they, like the KOT and ARDX20, are not leaving my pedalboard as long as I can play.

Great, great gear. I can't speak highly enough for it!

ARDX20 used by a pro December 19, 2012
Reviewer: Mike  

First, a little background on me: Professional touring and studio guitarist. I spend several months a year on the road touring all over the world and play/write music for tv, movies, records, etc. when I'm home in LA. Doesn't really matter, other than to give some insight into my experience or point of view, which may or may not matter, haha.

I'm a bit of a pedal nut and definitely am a delay nut. My main touring board usually has two delays. My most recent set up had a Strymon Brigadier and an MXR Carbon Copy. My all time favorite delay is an old school DMM, but they're fidgety, unreliable, and HUGE. I love the modulation on a DMM and love the gooey thickness of the tone, though sometimes its a touch dark/muddy.

I recently acquired an ARDX20 and the Amaze0. Spent a few days running it through the paces and I'm VERY impressed. It sounds fantastic. Very warm, very thick, and it blends with the sound of the guitar really well. My Strymon, and many of the other pedals I've tried tend to sound separate from the guitar. Sort of disassociated from the main guitar signal. The ARDX has that oneness with the sound like a DMM. Hard to explain, but if you've tried a DMM you know what I mean.

The tone is a little bit clearer and brighter than a DMM, but in a really good way. It is just a tiny bit less murky and it doesn't create a mudfest when used and/or abused. Even with a semi-hollow on the neck and a big thick tone it still doesn't get out of hand.

The amazeo is great, too. The tap tempo works as it should, imo. The Strymon never seemed to get the tempo I was tapping right. The AmazeO averages more than 2 taps in, which is great, and it seems really accurate to what I'm tapping. The modulation is really great too. DMMish, but it works at every setting without being super weird. The preset functionality works really well, too.

Right now I have it set so the top delay is a slapback, which sounds great, and the bottom delay is set with the Amaze0. I know there's a mod the make it affect the top delay, and I may try that, but I love the slapback so I might just leave it as is.

As others have surely pointed out, it is a bit big on the pedalboard, but since its two separate boxes it is a lot more flexible to position than other solutions. The Amazeo is super tiny and can kind of go anywhere. I also like that it runs on regular 9v power. It is worth the size for the sound and flexibility. I may venture down the road of using expression pedals and whatnot, but that might require a bigger pedalboard, haha!

I give this a big thumbs up and kudos to Mike for finally making a tap tempo analog delay that sounds great and is easy to use. I've tried them ALL, and this one is a keeper.
