This might sound weird (even for me). but here goes; My wife took painting lessons from a TV show, by a guy named Bob Ross (R.I.P.). I used to watch along, while she painted to his videotape. Whenever he wanted to 'blend' the paints together on the canvas, he would very lightly move the brush over the canvas. So lightly, he would hardly touch it. He would say "Left to right, ever so softly, use (on your brush) 2 hairs and some air." Lol. So now, whenever I catch myself digging in on the bass too much, I say to myself; "ever so softly, just 2 hairs and some air." Usually my hand relaxes and my touch on the strings lightens (both hands). I know it's weird, but a little mantra like that, when you catch yourself doing something you don't like doing, can help. The real trick is, to catch yourself doing it. That's a much longer discussion...
