Maxon AD-900 Analog Delay Pedal - $195 (alameda)
QR Code Link to This Post
One of the best and most organic analog delays. Early model with 2 chip MN3005 version. It comes with the original, properly functioning power supply.
Below is some of what others have said about this pedal:
MAXON AD-900 Analog Delay is a highly regarded effects pedal known for its warm, rich delay tones. It features a maximum delay time of 600ms and uses high-quality BBD (Bucket Brigade Device) chips for its analog delay.
The Maxon AD-900 Analog Delay is a premium pedal, revered for its warm, natural-sounding echo that only true analog circuitry can provide. With up to 600ms of delay time, it offers a rich, expansive soundscape, perfect for creating depth and space in your playing. Ideal for guitarists who value the subtleties of analog delay, the AD-900 is celebrated for its reliability, clarity, and the musical quality of its repeats, making it a standout choice in the realm of delay effects.
The AD-900 was designed to provide the longest, warmest, smoothest all-analog delay tone ever. Controls and features were kept to a minimum to free the circuit from unwanted noise and complexity of operation, as evidenced by the unit's simple three-knob layout and single output. Delay Time, Repeat, and Delay Level controls allow for precise adjustment of the delay effect with zero guesswork.
The AD-900 circuit runs at a higher voltage than typical analog delay circuits, which provides the unit with significantly more operating headroom. This increased headroom eliminates input overload distortion and creates a more accurate reproduction of the input signal in both dry and delayed modes.

The AD-900 Analog Delay was created after careful examination of other analog delay units (including the AD80). While most players voiced a preference for the warm, organic tone of analog, many complained about the short delay time (generally 300 milliseconds) that they were limited to. In addition, distortion and added noise due to hot input signals were becoming a common if undesirable consequence of analog circuitry.
The AD-900 was designed to eliminate these problems in order to provide the longest, warmest, smoothest delay tone ever.

Delay Time, Repeat, and Delay Level controls allow for precise adjustment of the delay effect with zero guesswork.

The 12-volt power supply (included) powers four Panasonic MN3008 (high voltage BBD IC's, now out of production) that offer 40-600 milliseconds of delay time. With this increased delay time a much wider variety of echo effects can be attained, from tight slap echoes and long trailing delays to overlapping "sound on sound" textures. The AD-900 is custom-calibrated for self-oscillation at higher Feedback settings, creating wild "ray-gun" and "UFO-landing" special effects.
