i just got a b-blender , the stock bigsby front roller and brass saddle sounded amazing with the b blender, but there was too much friction on the b string and it would snap after a day or two of practice with it. I didn't want to use the plastic replacement roller that comes with the b blender since it changed the nice tone of my guitar way too much. The b blender functioned great with the delrin / plastic roller but my guitar sounded like it was cheaper. So I ordered a callaham roller since it's stronger than a stock bigsby roller. The stock bigsby roller was getting all scratched up from the b string moving with the bender. and then I changed the first bridge saddle to a graphtech tusq saddle. Now it sounds great and the b bender functions very well. The tusq saddle seems to have no friction. I just played it this morning at church service and I had a lot of fun with the guitar. So fun to play.
