Still the absolute benchmark for BBD Analog Delays, the Maxon AD 999 Pro stands alone for Specs & Tone.

Seemingly impossible to find new & rarely seen used, this example is a rare find & great value.
In way above average condition for age, would easily qualify as excellent if now for the small blemish on the back. No visible major chips or scratches.

In 100% working order, no noisy pots or switching. All the multi-delay taps working as they should.

Pedal only , sorry, no box etc with this one.

Original specs from Maxon;

A genuine analog delay with Maxon BBD IC (MC4107D).

It features up to 900mSec. of delay time, largely outperforming its predecessor AD900.

AD999Pro has two outputs for effected signal and dry signal respectively.

High-performance Noise Reduction (which consists of RMS level sensor and high-definition VCA)

provides clear delay sound.

Improved low range response yields bold sound. Excellent balance between low and high range offers

clear and firm delay sound without spoiling warm sound of analog delay.

Single-Delay / Multi-Delay Mode is switchable with newly added tape echo multi-head simulation function.

In Multi-Delay Mode, midstream delay signals (which are taken from the middle of BBD delay circuit) are

added into normal delay signals. This feature provides extensive delay effects such as tape echo

multi-head simulation and ambience effect of a concert hall.

True Bypass Switching lets your instrument’s signal pass through a non-electronic bypass line

when the effect is disengaged, feeding your amp with direct, unaltered signal from your instrument.

Low noise mechanical 4PDT switch is used for effect / bypass.

Easily viewable LED to indicate effect/bypass.
