What power supply do I need for the Le Preamp series ?

If you wish to use a power adapter other than the one provided with your Le Preamp pedal, here are the specifications it will need to respect:


  • Voltage: 9 or 12 V DC. The power supply needs to be Direct Current (DC), you cannot use an Alternating Current (AC) power supply. You have to use a regulated power supply. 12V is preferred, but 9V should work ok too. Expect a little loss of headroom at the output stage.


  • Current: 500 mA or more. The Le Preamp series pedals use 500 mA of electric current. Any power supply delivering less than 500 mA will not be able to provide enough electric current and will not function, or may undergo some damages. A power supply delivering more than 500 mA can be used.


  • Connector: 5.5 x 2.1 mm. This is the standard-size connector for effects pedals.


  • Polarity: negative center. This is the most common type of polarity for effects pedals.


You will find here a list of a few pedalboard power supplies that could be used to power one or more Le Preamp pedals, along with a Torpedo C.A.B., and other pedals.
