Independent shopping perspective

The Korena take

9V power supply for Dunlop and MXR pedals. Buy it if you have a pedal that needs wall power instead of a battery.

Dunlop ECB-003 AC Adapter product detail
Product studyDunlop ECB-003 AC Adapter

Strong match

Who this is for

  • Running a single MXR or Cray Baby pedal off wall power
  • Players tired of swapping 9V batteries mid-rehearsal
  • Keeping a spare adapter in the gig bag as backup

Consider the trade-offs

When to look elsewhere

  • Powering a full pedalboard — this feeds one pedal
  • Pedals needing 12V, 18V, or reverse polarity
  • Anyone wanting isolated outputs to kill ground hum

What matters in use

The specifications, translated

Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01

9V AC adapter

Matches the standard pedal voltage. Check your pedal's rating before plugging in — wrong voltage can damage it.

Detail 02

Single output

One pedal per adapter. Daisy-chaining more requires a separate splitter cable, sold on its own.

Detail 03

Wall-wart form factor

Blocks adjacent outlets on a power strip. Plan a spot on the strip or use a short extension.

Detail 04

Made for Dunlop pedals

Jack size and polarity match Dunlop/MXR boxes. Other brands often use the same standard, but confirm first.

Final check

Know before you order

  1. 01Check your pedal's voltage and current draw against the adapter before plugging in
  2. 02No daisy-chain cable included — that's a separate purchase
  3. 03Adapter power can introduce hum that battery power does not

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01Will this work with my Cry Baby wah?

Yes — Cry Baby wahs use the standard Dunlop 9V jack. Confirm your specific model's power rating on its back plate.

02Can I power multiple pedals with it?

Not by itself. You'd need a daisy-chain cable, and total current draw across pedals has to stay within the adapter's rating.

03Does it come with a power cable?

It's a self-contained wall adapter with an attached output cable. Nothing else is needed for one pedal.

04Why is my pedal humming after I switched to this?

Non-isolated wall adapters can pass noise into the signal. An isolated power supply solves it if the hum bothers you.
