it's an oldschool method.... i've seen some vids and live performances, of classic players that used a piece of foam to kill the sustain on the bass.... usually finger played, but not always... and what it does, is make the attack of the initial note kind of pop out, seems loud in the mix, and then it decays off fairly quickly, allowing anything else in the mix to stand out, right up to the moment of the next bass note. seems to work best for notes that are done quarter-note.... so there's room in the arrangement for everything to shine.. and it allows the bass part to be mixed hotter, but then it doesn't swamp anything.. anways, just thinking out loud, i'm seriously thinking of trying this out. this would be for folks that are looking for a more classic 'p-bass' type of round tone. as much as i love modern bass sounds and recording, this tone is what resonates the most with me. thoughts?
