D'Addario PW-CT-9VF Adapter

9V Power Adapter for Guitar Pedals — Reliable Mains Power for Your Effects

The D'Addario Planet Waves PW-CT-9VF is a compact mains adapter that keeps 9V guitar effects pedals, tuners, and small processors running without the cost and waste of disposable batteries. It converts household AC into a stable 9V DC supply through a single 2.1mm barrel output, serving as a drop-in replacement for the wall-wart adapters that ship with most pedals. The PW-CT-9VF is the F-Style plug variant of D'Addario's 9V power adapter line.

What Sets This Power Adapter Apart

Unlike generic third-party adapters, this unit has a universal input that accepts 100V to 240V AC, so the same adapter works on tour across continents without a step-up transformer. The 2.1mm barrel plug with center-minus polarity matches the standard used by the vast majority of guitar pedals.

Electrical Output — Stable 9V DC for Pedal Circuits

The output stage delivers the voltage and current that most individual analog and digital pedals need to run cleanly, keeping analog circuits free of the noise and sag that creep in when batteries weaken.

• Output Voltage: 9 V DC — the standard rail for stompbox pedals and tuners
• Output Current: 500 mA — enough headroom for most single-pedal loads
• Polarity: Center Minus (Tip Negative, Sleeve Positive) — matches the standard pedal power convention

Input & Compatibility — Universal Mains Voltage

Built for international use, the adapter accepts the full range of mains voltages used around the world, so the adapter can travel with the player without a separate converter.

• Input Voltage: 100–240 V AC — universal mains compatibility for international touring
• Number of Outputs: 1 — single-pedal dedicated supply
• Adapter Shape: Barrel (2.1 mm) — fits standard pedal power jacks

Build & Practical Use — Designed for Live and Studio

At home on a pedalboard or behind a desk, the wall-wart form factor keeps the adapter out of the way, while the long cable simplifies cable management in both home and touring setups.

• Cable Length: ~183 cm (72") — reaches from outlet to pedalboard with routing slack
• Power Source: Mains (not battery-powered) — continuous power without battery swaps
• Ideal Use: Live performance and studio sessions
