  • Eh mxr-m80 weakness

    Hi all
    I read on several forums about the pedal dying after pushing a switch.
    After removing the PCB, it was clear to me why this can happen.
    The casings of the pots are "floating" only 1mm above the electronic components, and i can imagine that when you're "in the heat oh the battle" (on stage) and you need to push a switch, but your foot is a little out of position, you don't think about those knobs that are only a few inches away... you press it with enough force, and... silence .
    Or if for example a bolt has loosened.
    In this case it caused a short circuit and it totaly fried the TLC2264C !!
    I don't understand why EH didn't saw this coming !
    For a pedal that costs 179€ in Germany, you'd expect better.
    As i own this great sounding pedal, i built a simple modification to prevent it from happening.
    I just added a mylar between the pots and the components. (see pics)
    I also added a CLEAR schematic, which was hard to find !!

    I replaced a number of pots on these pedals.
    Good call.
