Getting the FRFRs and playing at louder levels made feedback noticeable with the FM3 when using a tube driver cranked up on a clean amp (3 knob on clean Marshall or Mesa Lonestar like when Andy Timmons tone chasing) I get crazy feedback if I am not turned a certain way with my guitar's bridge pickup selected. It's not microphonic, it's with any of my guitars (and I can't talk into it). Coil splitting and bridge with the neck pickup is quiet with no feedback. This is not cool feedback, it's an annoying loud hum, it is frustrating at any kind of usable volume. Is there something else I can do besides find the place in the room to stand? Thanks and take care everyone!
