I joined this website recently and have learned a lot from you guys, stoked!\ I was hoping you guys could offer you expertise with an issue I'm having with my equipment.
It's my live setup and really basic... Just a Line 6 Flextone HD II hooked up to a Marshall 1960 Lead cab and a guitar. I have recently added some accessories like a cordless system, Boss NS-2 and a Boss CS-3. With or without the cordless system I'm getting some terrible feed back when any quick palm mute is made or an abrupt stop. It will also do this when both pedals off and just in line. If I line a chord just straight to the amp, problem free. I have used multiple sets of chords and used a different guitar. I have used the pedals on another amp, I think a Peavey 3120 without issue, again problem free. I think it's pretty obvious that I'm a rookie when it comes to equipment but I have tried to learn what I can from this site. LEt me know if I left something out as I'm not sure how to describe this exactly. Any suggestions? Thanks in advance!
Have you checked the batteries or power supplies for everything? tried them one at a time? in the fx loop or straight into the front of the amp?
