Hi Myles,
I notice with my Mesa/Boogie F-50 widebody combo, the tones only sound good when heard from a fairly steep angle - that is, either above or to the side of the amp. Directly in front, it sounds very harsh, bright and "stabby" if that makes sense.
It sounds fine if I throw, say, a blanket or sweater over the amp.
Is this likely related to the speaker? It has a Mesa Black Shadow 12". If I swap that for something else, could it potentially make a positive difference?
I've tried using and external EQ to see if that helps, and it doesn't make a significant difference.
Thanks,
Colin
