With the knowledgeable, fantastic service Jason at Bassstringsonline provides, I personally have no desire to buy my sets anyplace else. Add in TBer VIP pricing, Wow!!!!
Jason also recommended Infeld Superalloys to me (spot on and I'm loving their tone) and took the time to guide me through the measurements from my bridge saddles to tuning gears to ensure I was buying the correct length set.
And when I say he "guided" me, I mean he practically drew me a picture because I sometimes can be a bit slow to figure things out.
