First of all,sorry for too noobish question...I recorded for years never really think of is this totally right thing to do.I talking about audio signal level for heavy distorted guitars.... Buddy of mine who doing a mixing a lot put a worm of suspicious into me when he sad that every tracks he got online from heavy metal music guitars are always -10 to -12db... I need your opinion(s) and experience of pros on this basic question. Thanks in advance. Best regards.
