    The title sort of says it all. It's not as simple as testing one pedal/cable at a time, because it just randomly happens for literally a minute or two and then it comes back. It has happened with both bass and guitar so I don't think bass/guitar/amp is the issue.

    Any trouble shooting tips for this sort of thing?

    How often does it happen?

    If it happens every 3 minutes I would simply yank one pedal at a time from the board.

    Of course, if it only happens ever hour or so that would take a lot longer for my method to work.

    I would estimate it happens once every few hours of playing time.
     
  4. Take away half the board, see which half faults, again, again, again. How big was that board? Ok once more.

    OUCH! That greatly increases the amount of time it will take by simply playing with different variations and combinations. Because things get exponentially more complicated when you have to factor in power supplies and cables...... which could also be causing the problem, not a pedal at all.

    Seems as though it is time for measuring and testing on an electronics level.

    It was happening to me too, turned out to be a loose connection inside my loopmaster.

    this happened to me when i was using those damn Lava solderless ELC's!

    the problem was quickly solved when i threw all of them out and swore to never use them, just kidding, i sold them... i am just glad people still buy that overpriced piece of headache

    I am hoping it is just a cable but identifying it will be a pain unless I just start fresh.

    My experience too.
     
  11. The unfortunate truth of large pedalboards. They're fun and subjectively versatile, but the imperfections become more pronounced the busier the board gets. Could be a cable, jack or a buffered pedal getting smoked amidst everything else that could go wrong. I hope for your present's sake and your fellow pedal breeders' future's sake that you are able to rectify the problem and report back to us.
     
  12. Pedals in use goes 16, 8, (8), 12, (12),14, (14), bingo

    (2nd trials if fault doesn't appear in selected set)

    The possibility of accidentally "fixing" a dodgy cable during all of that doesn't bear thinking about. Ideally you would find the fault present until the last trial.
