So i just bought my second 6505+ i had and sold one awhile back and regretted it immediately, but i got this one used and everything is pretty much new. I noticed when i change channels i get this glitch like noise? This is changing the channel from the amp as well so it cant be a wire or footswitch cause i dont have one lol. Also along with the noise the led for whatever channel im switching from will flicker before it switches to the next. For example if im going from my rhythm to my lead the green led will go off go back on and than go to the red lead one. If any of you guys have any ideas it would be greatly appeciated.thanks
