IMO it's not even the right mids they should emphasize either
And they still overemphasize it regardless
I have my 6505+'s mid set at 2-3 (not 2-3 o'clock, 2-3 on the label) and that thing still has plenty of mids playing through Greenbacks, or with Greenback IRs
Meanwhile the "modern" metal guys are using 6505s (even more low mids) set up at 666 with a tubescreamer in the front, playing through V30s.
Bruh.
