Hey everybody, I'm new here. I might post a real intro in the intros section later, but onto the issue I'm having... My DSL5C makes an audible popping sound when I switch from the Ultra Gain Channel to the Classic Gain channel. This happens regardless of whether I use the front panel button or the footswitch. I've read about this problem several other places online, but none seem to have any definitive info. Here's a youtube video of the same exact issue I'm having: https://www.youtube.com/watch?v=jB6qkAqAbyc The person who posted the video said that all the DSL5C amps he tested had the pop. So, my question is to you all: Do your DSLC's have this pop sound when going from the Ultra Gain to clean channel? Thanks!
