Just got this mint, new to me PP. Signal chain: X2>TU2>Phat Phuk>BDDI>Compressore>Fdeck>CMD102p>Shure 900 in-ears. During setup the band asked me to not use it as the popping was loud enough to hurt/bother them. It is louder going on than off. I tried it with and without daisy chain. The original owner had no issues with it. The BDDI has a similar button/switch and is silent going on or off. Ideas?
