so playing on a schecter diamed series damien platinum my palm muting tone seems to die when playing master of puppets i tweaked the action/string tension still sounds dead i did that because theres slight string buzz but its not very noticable. But any who i cant seem to get the palm muting to come through when playing i used to be able to get clear palm mutes on master of puppets but now i cant. playing without a backing track though they sound fine. why is this?
Not 100% sure but judging by how it's audible without the backing track I might say that you need to EQ your guitar a bit more to get it to cut through. Maybe try bringing up some of the mids.
