🔌 What Is It
📐 Principle
Converts 220V AC→9V DC. One adapter=one pedal (or daisy chain). Filtered, regulated. 2.1×5.5mm barrel connector.
🎵 Why Specialized
DON'T use generic adapters! Cheap=unstable, noisy, damage risk. Specialized (Boss, Dunlop): regulated, filtered. Difference=clean tone.
📐 Adapter vs Battery vs PSU
Battery: 1 pedal, convenient, dies. Adapter: stable, 1–4 pedals. Isolated PSU (Voodoo Lab, Cioks): pedalboard 5+. 1–2→adapter. 5+→PSU.
⚡ Key Specs
📐 Voltage
9V DC standard (95%). 12V: Strymon, Line 6. 18V: OD headroom. ALWAYS check! Wrong voltage=damage.
📐 Polarity
Center-negative (−): standard 99%. Center-positive: rare (old EHX). Wrong=damage!
📐 Current (mA)
Adapter mA≥pedal. Analog 20–100. Digital 100–500+. 500mA adapter→50mA pedal=ok. 100mA→300mA=NOT ok.
🏆 Models
📐 Boss PSA-230ES
9V 500mA center-negative. ~$25. The standard. For all Boss and most others.
📐 Dunlop ECB003
9V 660mA center-negative. ~$20. For MXR, Dunlop. Higher current.
📐 Truetone 1 Spot
9V 1700mA center-negative. ~$25. For daisy chain (5–8 pedals). NOT isolated.
🔗 Daisy Chain
📐 What
Adapter→splitter cable→multiple pedals. 1 Spot+MC5=most popular budget. Adapter mA≥total of all.
📐 When OK
2–4 analog (Boss, MXR). Same voltage. No noisy digital.
📐 When Not
Digital+analog=noise. 5+ pedals. Mixed voltages. Serious→isolated PSU.
🏷️ Brands
📐 Boss/Roland
PSA-230ES: 9V 500mA ~$25. Standard. ACA: vintage Boss (12V unreg).
📐 Dunlop/MXR
ECB003: 9V 660mA ~$20. ECB004: 18V. ECB006: 9V AC. Versatile.
📐 Truetone/TC/EHX
1 Spot: 9V 1700mA ~$25 (daisy). TC PowerPlug: 9V 670mA ~$15. EHX 9.6V DC. Harley Benton ~$8.
