I think my Headrush unit might be busted but I just wanna check here first. This is a brand new unit since my last one was broken and Sweetwater replaced it, which is making me think Im just unlucky or these things are junk. Ive gone through many presets and Axe-Xchange presets done lo/hi cuts/ modified output 2 EQ and my Headrush monitor just keeps making all these weird warbly noises and fast paced thumping noises. Happens on both inputs of the Headrush unit. Any FM3 settings I should check or you think the speaker is busted?
