  • Piezo spike suppression with leds

    Ok so this may belong in the pickup lounge
    but here is the question

    Back some time ago. Joe gore had an article About spike suppression in a guitar cable using two polarity opposed red LEDs
    Mounted in a guitar cable
    between the signal and ground

    ​​​​​​I can't find the article
    But I was thinking this could do some of the compression on my piezo bridge that seems to be a bit spikey

    Does anyone remember this
    Does anyone have any thoughts on this

    It's the Kiash piezo bridge from Amazon
    It's about $25

    Id be interested to read it if you find the article. I have an RMC piezo system in a Brian Moore guitar, and it is super spikey. I've always had to use compression to make it usable.

        I use that physically on the inputs to my interfaces. If you install it correctly (assuming you put it on a cable) you won't be able to A/B it with a stock cable run into an amplifier. The LED's serve to clip the signal transients to levels that won't mess with digital interfaces.

            Are your piezos passive or active?

                The ones I use are active, so this might not work.

                  It should still work as clipping is a function of amplitude. It will work with any instrument level signal
