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.

Independent shopping perspective
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.

Detail 01
Matches the standard voltage for most stompboxes. Check your pedal's label — some analog and high-headroom pedals want 12V or 18V.
Detail 02
One pedal per adapter. Daisy-chaining several pedals off it depends on the total current they draw.
Detail 03
Takes up space on a power strip and may block the adjacent outlet. Worth checking on a crowded board.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It works with pedals that take 9V and match the connector and polarity. Check the label on your pedal's power jack first.
Only with a separate daisy-chain cable, and only if the pedals' combined current draw stays within what this supplies.
Some pedals include power and some don't. If yours arrived without an adapter, this covers it.
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.
