    Hey guys,

    Please bear with me as electronics aren't exactly my forte, hence I thought it would be best to ask you guys as you know your stuff surely. :)

    I've got a guitar pedal without an ac/dc adapter (currently runs on batteries only).
    Can I use computer's ac/dc adapter as an electricity source?

    Guitar pedal: 9V 300 mA

    Toshiba adapter: input 100-240V-1.6.A 50-60hz
    Output 19V-3.42 A

    The adapter says 'for use only with information technology equipment'. To my understanding guitar pedal's output is 9V and computer adapter's 19V, which seems to make it incompatible, or at least risky as f**k to use together, correct?

    Many many thanks for your help!

    The pedal's input, not ouput is 9V. Stuffing 19V into this would soon loose the smoke out.
    Get a 9V DC power supply and make sure it is connected the right way round.
    You could also get a buck convertor to go from 19V to 9V but this just gives complication for little advantage.

    Agreed. Low-power wall-warts are cheap as chips these days.

    A 9VDC wall-wart might not have enough filtering so might might produce a hum sound from the pedal.
