    Is it possible to run a pedal backwards? Like going in the output and out the input? My brain tells me it will probably just not send a signal, but could it? Would it cause any harm to the pedal or any of the other gear involved? Again, I figure it would simply not do anything, but I’m curious.

    Ever hear of a "Bouncing Betty" land mine? That's what could happen when you step on it.

    It should not hurt the pedal, but that's the only good that will come from it.

    I've mixed up input/output on TS a few times over the years. No signal gets from guitar time amp.
    No worries, it's never caused damage:oops:

    in the pink floyd song Echoes the seagull sounds were created by David Gilmour hooking up a cry baby backwards ( in/out puts reversed) causing the filter to go into oscilation and controlled by the filering effect of the pedal . he then had Pete Cornish actually build that into his cornish pedal board to use the effect live.

    Yes, the crybaby trick on Echoes.
    But, I have plugged an old Memory Man, backwards, and it didn't do it any good.

    I am not aware of any pedals that will work backwards as designed.

    Solid State devices are doped to only work one way. This is why some transistors and PNP and others are NPN. If you hook it up backwards, the electrons can't fall in the holes ( they can't go uphill! )

    This sound likes a load of horse stuff, but its a very top-level description of how they work. ( Does anyone really understand how they work? )

    It s actually the first thing people troubleshoot when they are plugged in and no sound comes out. They check their pedals to see if the guitar is not in the output end.

    True bypass may work.

    That's only as far as DC is concerned I think. Plugging the guitar into the output of the pedal changes nothing about that.

    To operate correctly, as intended that's true, but they will often still 'work' when hooked up backwards.

    I guess the reason it won't work is that the (audio) signal will enter at the collector or emitter (transistor or opamp) while it should enter at the base for it to amplify and come back out at the 'other end(s)'. But people that know more about this may prove me wrong, in some way or another.
    Maybe I should go and try all my pedals backwards and see what happens. :)

    I do it by mistake all the time. It's one of the things I look for when I trouble-shoot.

    Doesn't damage anything. Just doesn't make any sound.

    Make sure you use a directional cable.

    No signal gets through, I run a fuzz face the wrong way once due to the backwards input/output on it. It would not work after doing that. Not sure if that was the reason stopped working but it worked fine the previous times I had used it correctly.

    I remember going in through the out door by accident on my entire pedal board, and just a faint signal got to the amp. Took me about half an hour to figure out that I had reversed the path - kept replacing cables and stuff. Sucked, 'cause my friends were all playing and I was missing the jam. Idiocy at it's best.

    My family actually prefers it when I plug mine in backwards. Then they don’t have to listen to my guitar playing.

    The best thing about your kind of question is that—when it doesn’t lead to injuring you or your equipment—it can lead to new sounds.

    Back in the late 40s/early 50s some guitarist asked themselves, “This is probably a stupid question, but what if I turn this amp up all the way?” A few years later someone asked, “What would happen if I stuck the pickup selector switch on my Stratocaster in the in-between position?”

    Hendrix used the same technique on Electric Ladyland to simulate seagull sounds.

    I tell you what you DON'T want to do, and which I did last year . . . accidentally plug a 12v power supply into a pedal that needs a 9v power supply.

    Result: deep fried pedal.

    Yep. I fried my DS-1 as a teen because my 9 volt batteries died and I just grabbed a random wall wart to power it.
