18v into 9v OD Pedal

    What experience do you all have with pushing OD pedals with extra voltage? I want to give my Canyon pedal even more headroom and have the power supply space, but also don't want to blow anything up.

    Don't do it unless the manufacturer specifically says that you can, for starters.

    Oh, I probably wouldn't unless I knew someone had already tried it. But some pedals can do it, even when not specifically listed, and sound great.

    You could probably confirm directly from EHX. @Corythosaurus is the rep, I believe.

    18v doesn’t always make a circuit have more headroom unless it was specifically designed that way. For instance, the Dr. Scientist The Elements can do 9-18 and it doesn’t change anything in the headroom department at all. However, I’ve tried other ods or dirts that you could hear a dramatic change, but it’s not often.

    It is the Hot Wax anyways so I am doubtful. But I REALLY want to try it. It might give me a reason to get a Darkglass Vintage.

    Yeah, it's the same with some Empress and some Broughton Audio pedals.

    Generally speaking, electronic circuits DRAW power. Power isn't PUSHED into them. So the pedal will only take what it wants.

    I think I did read that one of the high-end LPF/HPF/Pre pedals (maybe Broughton?) gained headroom from higher voltage to a point. But I don't think that is very common.

    So while there may be some pedals that benefit from higher voltage, if I had to bet I would say the Crayon isn't one if them.

    If you want it to have more headroom, I suggest boosting signal in front of it, not voltage.

    Keep in mind that I do repair electronic equipment for a living, but I'm new to pedals. So there's a chance I'm FOS. :D

    Man, I teach Philosophy for a living. I appreciate the advice because the only thing I know about pedals is that knobs+bass=music.

    But does it really = music? Or could it just be sound? And if no one is there to hear it, is it sound at all? And did turning the knob really do anything to the sound, or did you tweak your perception of how it sounded?
    :D

    Oh, let us be completely honest. I make rather barbaric noise that merely aspires to music.

    It was a sad attempt at a philosophy joke. :(

    You are talking about current, not voltage. Over supplying voltage will definitely fry some pedals. Beware.

    Nope. Voltage. From the Broughton page.

    "The pedal can be powered by a 9V battery or a DC power supply (not included). The DC supply should be a standard Boss style connector, center negative polarity. The pedal can accept 9 to 24 volts. Higher voltages will provide more clean headroom. The current draw is approximately 10 mA."

    But I get what you are saying about the word "draw". That was misleading.

    I was not talking about the HLPF or its capacity to use 9-24v. I was talking about this sentence:

    "Generally speaking, electronic circuits DRAW power. Power isn't PUSHED into them. So the pedal will only take what it wants."

    That is current, not voltage.

    If the box says 9VDC then you should give it 9VDC.

    Let us not overcomplicate our lives and release the magic smoke, eh?

    Most pedals don't have an internal regulated power supply, so operating voltages and circuit currents vary directly with input voltage.

    EH specs the Crayon and Canyon pedals for 9.6VDC. The device may operate at higher voltages and even sound better, but not without risk.

    Just because someone has tried it doesn't mean that it was a good idea to do it. Always check with the manufacturer to see if higher supply voltages are safe.:thumbsup:
