This 3 step power supply uses an ICL7660 charge pump and creates three available output voltages from a single standard 9V power supply: +17V, +25V and +33V.
Why would you want to use a higher input voltage for your effect pedals? This 3-step power supply is specially useful when used with boosters, overdrive and distortion pedals:
– In clean boosters, when the input signal is too loud, the pedal starts distorting it instead of just raising the volume. With a higher power supply you can apply louder input signals and the booster will amplify them without distortion
– In overdrives, distortion, fuzzes… a higher power supply means that the pedal will have a higher headroom
Note: always be careful and check that your pedals are compatible with more than 9V, otherwise they might get damaged!
