I'm not having that problem... yet... but I do have a question as to how you're using the direct out; are you plugged into a 4X12 cabinet and using the direct out? Or are you going direct out to the PA without plugging into a cab?
Can I use the direct out on my hd100 without plugging it into a cabinet, like as for recording and live performances? I want to be able to set my head on my recording desk and go direct out to my audio interface
