It seems on my POD HD500, whenever I press a footswitch to turn off a certain effect for example, an asterisk* appears. When I press it again to turn that footswitch back on, I noticed the volume's not as loud as it was before I touched it. I have to quickly change to a different preset, and then back for it to be normal again. This happens with every preset I've tried, whether it's a factory preset or one of my own. I play in a church band and the sudden change in volume is killer when I'm engaging or disengaging an effect mid song. Any solutions?
