Ok a little background... I used to play a 4 string Marcus Miller Jazz and I always rested my thumb in the bridge pickup and really dug in. Recently I've made the switch to a 5 string pbass that I strung with Chromes, in in love with the sound and feel, but I've noticed that I get the best tone if I play closer to the neck and rest my finger on the pickguard. The problem is, I HATE how loose the string tension is there, as I like to really dig in when I play. Can anyone help or recommend high tensions flats?
