Love this!! Haha, I'm breaking a string about once every three or four months, which is good because it's a reminder to get fresh strings on! It's all in enthusiasm and plucking technique, (for better or worse). Playing heavier music with fingers, I like to accentuate certain notes by plucking down into the bass body, the string slaps off of the fretboard and gets a killer tone through an overdriven tube amp (Steve Harris plucks like this a lot). My singer calls it the "gank", gankin' on the strings to get that dirt! Gankin' the soul right out of the strings!
Love playing hard, fast and heavy!
