I was wondering what effect string gauge has on the sound. I've been using 45-105 rounds on my Fender Am. Jazz and 50-105 flats. I think I'm going back to flats though. I played my buddy's MIM Jazz w/the stock strings, and I noticed they are much thinnner gauge than I've been using. I could actually do a string bend on his bass, whereas on mine it's like trying to move a stationary object. Anyway, I'm looking to buy another set of flats soon, so I'm just wanting some recomendations on what gauge to purchase.
