Every time I see video of Hendrix using his FF, he's using his neck pickup and it sounds great. When I use mine it sounds muffled and too bassy. I've tried turning up treble on my amp and guitar but it still sounds like shite. The only cure is to use my bridge pickup. I'm running the FF through a Lovepedal Purple Plexi and a Katana 50 set on clean. Iv'e also had this problem using other amps. Should I get a different fuzz pedal?
