I've got a condenser microphone and was wondering where I should place it in terms of my amp's speaker to get the best recording tone?

Thanks in advance...
try to put in between the Speaker and the side of the amp normally the sweet spot is in there some times
I like to point it dead center, then angle it off to the side about 15 degrees.
My stuff:
Fender Tele 60's Reissue
Schecter Blackhawk
Vintage V300 acoustic
Yamaha RB170 Bass

Peavey Classic 30 amp

Boss SD-1, DOD Grunge, Guyatone PS-010 Compressor, Marshall SV-1, Vox V847, Zoom G2, Line6 Echo Park
