Ibanez AD9 Analog Delay

The Ibanez AD9 Analog Delay is a compact delay pedal made by Ibanez, produced in its original form from 1982 to 1984¹. It is a true analog delay, built on bucket brigade circuitry, with three knobs controlling delay time, delay level, and repeat, and a 300 ms maximum delay time². Players prize it for warm, inviting echoes and its ability to self-oscillate when the repeats are pushed.

What it is and what it does

The AD9 sits in Ibanez's 9 Series, the same era of compact pedals as the TS9, and also appeared as the delay section of the UE 305 multi-effect unit⁵. RockBoard describes it as a high-quality analog delay effect pedal with a 300 ms time effect, allowing for a wide range of delay times and repeat settings². Its three knobs give direct control over the delay time, the delay level in the mix, and the number of repeats².

Because it is a bucket brigade design, each repeat darkens and softens slightly as it passes through the chip chain, which is the character analog delay fans chase. EarthQuaker Devices' Patrick Benson summed up the pedal's appeal in a beginner's pedalboard guide as "Bucket brigade analog goodness in hot pink!"⁴. Analog Man's David Szabados makes the same point from the repair bench: "the character of a good analog delay is thoroughly enjoyable and difficult to capture from anything other than a genuine" analog circuit⁶.

How it differs from other Ibanez delays

Ibanez has built many delay pedals over the decades, and the AD9 is the analog cornerstone of the line. Related models include the earlier Ibanez AD-80 Analog Delay, the Master Series Ibanez ADL Analog Delay, the 10 Series Ibanez AD99 Analog Delay, and later digital designs like the Ibanez DE-7 and the modern Ibanez LD303 Layer Delayer. The AD9's distinction is its short 1982 to 1984 run and its reputation among players as the one to have.

What reviewers and players said

Tim Mahoney, guitarist of No Use for a Name, named the AD9 his favorite delay in a Premier Guitar interview on his top five oddball pedals⁷.

He described what it does for his sound: "I love how the notes decay into one another with an added shimmer, plus you can get crazy self-oscillation action"⁷. He uses it live to thicken his clean tones with a short delay, and pointed to "Made in the Shade" as an obvious song to hear its shimmer and warmth⁷.

Pedal of the Day's review called it "a fantastic echo effect, one that is revered by delay enthusiasts the world over," with "a lot of warm and inviting echoes waiting to be heard"⁵. On That Pedal Show, comparing a vintage AD9 against other analog delays, the presenters came down on the side of the old units: "I'm a sucker for the old stuff"³.

Self-oscillation and the analog character

Self-oscillation is the AD9's party trick: push the repeat control far enough and the echoes build on themselves into runaway feedback, a behavior Tim Mahoney highlighted as "crazy self-oscillation action"⁷. This trait, shared with other bucket brigade delays, is one reason players still seek out vintage units rather than digital emulations, and it makes the pedal usable as a sound-design tool as well as an echo.

Collectibility and finding one today

The original AD9 was produced for only about two years, and TONEHOME, a vintage effects specialist, rates its collectibility as high while noting availability of units as good as of October 2026¹. On That Pedal Show's demo of a vintage unit, the pedal was described as "Only available used"³.

TONEHOME also hosts free PDF downloads of the original documentation: the owner's manual, the service manual, and the schematics¹.
