Can I use any 9V adapter for guitar pedal?
When a pedal says “9 – 18V”, it means it can accept voltages anywhere within that range. That means you can use a 9V power supply, a 12V supply, or an 18V supply without any problems.
Do all guitar pedals use the same power supply?
Most pedals, such as BOSS and MXR, require regular 9V power so pretty much any pedal supply will do. However, some do require a higher power supply such as some older Electro Harmonix pedals but usually if something needs a higher power supply the manufacturer will include the appropriate power supply with it.
