Electro-Harmonix 9V Power Supply

Independent shopping perspective

The Korena take

A 9V adapter for Electro-Harmonix pedals. Buy it if your pedal shipped without power or you need a spare for a single-pedal setup.

Electro-Harmonix 9V Power Supply product detail
Product studyElectro-Harmonix 9V Power Supply

Strong match

Who this is for

  • Powering one pedal that arrived without an adapter
  • A spare kept in a gig bag as backup
  • Players running one or two pedals without a board supply

Consider the trade-offs

When to look elsewhere

  • Powering a full pedalboard — this feeds one pedal
  • Pedals that need 12V, 18V or a different connector
  • Anyone who already owns an isolated multi-output supply

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 output

Matches the standard voltage for most stompboxes. Check your pedal's label — some analog and high-headroom pedals want 12V or 18V.

Detail 02

Single output

One pedal per adapter. Daisy-chaining several pedals off it depends on the total current they draw.

Detail 03

Wall-wart form factor

Takes up space on a power strip and may block the adjacent outlet. Worth checking on a crowded board.

Final check

Know before you order

  1. 01Confirm your pedal's required voltage and polarity before plugging in
  2. 02No daisy-chain cable included — that's a separate purchase
  3. 03One adapter powers one pedal; a full board needs a multi-output supply

Product questions

Before you decide

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

01Will this power any 9V pedal?

It works with pedals that take 9V and match the connector and polarity. Check the label on your pedal's power jack first.

02Can I run several pedals off it?

Only with a separate daisy-chain cable, and only if the pedals' combined current draw stays within what this supplies.

03Does it come with the pedal?

Some pedals include power and some don't. If yours arrived without an adapter, this covers it.

04Is this an isolated supply?

It's a single-output adapter, not a multi-output isolated unit. If you're chasing noise across a board, look at an isolated supply instead.
