Analog.Man ARDX20 with AMAZE0 Controller

October 24, 2011

This dual delay unit offers two independent delay channels—Red and Yellow—each with its own set of controls, so you can have completely different delay settings for each channel. When powered up, two yellow LEDs flash back and forth above the logo, indicating the speed of the current delay setting. The left footswitch toggles between the two delay channels, and the right switch turns the delay on and off. Maximum delay time is listed as 600 ms, though I got readings of 640 ms on the display of the AMAZE0 controller (Analog. Man’s Mike Piero says the max time is typically closer to 650 ms). Either way, it’s enough for most applications that don’t require long delays.

On the back are four ¼" jacks: audio input and output, an expression pedal in that doubles as an input for the AMAZE0 control pedal, and an effects loop jack. None of these jacks are labeled (a slight annoyance), and it’s also hard to read the low-contrast knob names on the face of the pedal.

The expression pedal jack lets you connect a pedal (such as the Boss EV-4 or EV-5), which can be used to remotely control the delay time of the Red channel. The effects loop jack accepts a stereo Y cable, and is active on whichever channel is selected when the delay is on. You can also get a 100 percent wet sound from the effects loop jack using a specially wired Y-cable (ring on the pedal side connected to the tip of the output cable). If you make or order such a cable, you can then use the pedal with a parallel effects loop.

To unlock even more features, connect a ¼" TRS stereo cable (not included) into one of the jacks on the AMAZE0 controller. This cable sends control data between the pedal and the AMAZE0. Now, as long as you’re on the Red channel, you can access tap tempo and also control the ARDX20’s modulation effects, which are designed to add tape delay-style warble, from the controller.

The AMAZE0 doesn’t take a battery, but still requires 9-volts, so you’ll need a second (optional) adapter for it. Alternately, you could power the AMAZE0 with an adapter and the ARDX20 with a battery. According to Analog.Man, the ARDX20 draws very little juice, and battery life is estimated at a whopping 30 hours.


The Analog Man ARDX20 is a dual delay pedal that has many additional capabilities when connected to the AMAZE0 controller pedal.

The AMAZE0, which has a 16x2, blueand- white LED display, gives you two different control modes, which can be toggled between by holding down the left footswitch on the controller. In Tap Tempo mode, you can not only tap in the tempo, but also control the two modulation parameters: Modulation Speed and Modulation Type (there are five sine wave modulations and five tapedelay emulation effects). In Program Mode, you can step between nine preset programs and edit their modulation parameters. One of them—Preset 0—lets you adjust delay and modulation settings with the knobs. Overall, the modulation effects work very well to simulate the sound of a tape delay.

The combination of ARDX20 and AMAZE0 gives you a delay rig that’s comprehensive and sounds great. My main concern with this setup is the number of cables necessary to run it (one or two power supplies, and stereo cable to connect controller, audio input, and output), which makes hooking it up a bit of a spaghetti fest. However, if you just need analog delay and don’t care about modulation effects or tap tempo, you’ll be happy with the ARDX20 on its own.
