Something I noticed the other day. There was an audible pop from I believe the PA when I activated the footswitch on my Korg Pitchblack tuner. My signal chain: Bass > Pedalboard (Pitchblack 1st) > DI 1. DI > PA 2. DI thru to Combo Amp (TC 250-112) Is this normal for people? Does this mean all my pedals will pop throught the DI if I hit the footswitch?
