I have been using a Headrush FRFR 12 inch cab for 2 weeks now. I have dialed a few tones that sound pretty good through it. Im using a Schecter sls dual humbucker guitar with EMG 57/66 pickups. When I download other peoples patches most of them sound thin to my ears. I would appreciate feedback on whether or not you think these patches have to much air or low end to them.
