I have the ceramic TT's. The alnico versions may take some time to break in and sweeten up.
I'm surprised that you didn't order "Da Bomb" setup...2 TT ceramic hemps and 2 TT alnico hemps.
That is supposed to be the ultimate Tone Tubby setup from what their website states.
Be a bit more patient with the alnicos, as they will have (or should have) a bit more presence, but as they break in, they keep getting better sounding.
