Zoom AD-16 9V AC Power Adapter for Zoom Guitar and Bass Effects Pedals

Zoom AD-16: The 9V Supply Behind Zoom's Effects Pedals

The Zoom AD-16 is a 9V DC AC power adapter made for Zoom's guitar, bass, and acoustic effects pedals. From the compact G-series and B-series multi-effects to the MS-50G, MS-60B, and MS-70CDR MultiStomps and the AC-2 and AC-3 Acoustic Creators, this is the supply Zoom specifies. It delivers a regulated 9 volts at 500 mA with center-negative polarity, exactly what these pedals expect, so tone and headroom stay consistent. For a pedalboard that lives at a fixed rig, it is the natural power source.

Zoom AD-16: No More Battery Swaps Mid-Set

Effects pedals run their batteries down fast, and a fading 9V can sag a pedal's tone before it dies outright. Running a Zoom pedal on the AD-16 removes that variable, so a G-series or MS MultiStomp performs the same at the end of a three-hour rehearsal as it did at the start. That reliability matters on stage and in the studio, where a dead battery in the middle of a take is more than an inconvenience. Plug in once and stop thinking about it.

Zoom AD-16: Correct Polarity Protects the Pedal

The AD-16 uses a 5.5 x 2.1 mm barrel plug with center-negative polarity, the standard Zoom pedals require. Matching that polarity matters, because a center-positive supply of the wrong rating can damage a pedal's circuitry. Using the specified adapter takes the guesswork out and keeps the voltage and current in spec. A regulated output also keeps noise out of the signal path. It is the safe, correct way to power the gear.

Zoom AD-16: Who Needs It

Any player running a Zoom guitar, bass, or acoustic pedal from a wall outlet needs the AD-16, whether powering a single MultiStomp or feeding a board. It is the 9V pedal supply and is not interchangeable with the 5V AD-14 or AD-17 recorder adapters. Keep one on the board and a spare in the gig bag. For consistent, battery-free pedal power, it is the right adapter.
