OK, I tried a .125 DR Marcus Miller (because that was the only set GC had with a .125) my theory, which Edwin confirmed was right, the smaller B sounded much better as far as tone & resonance, but it was horrible on the buzz factor. I tried giving it more relief & even raising the action from a .07 to a .1, & it still buzzed! So I put the .130 back on & ordered a .124 & .130 Circle K string & will see how they do. I just don't understand why I can get really low action on the E string with no buzz at all & the B which is 1/2 away buzzes. I know the bigger the string, the more elliptical vibration it will have, but my Schecter doesn't buzz on the B & I have played other 5 string basses that had good action on the B & didn't buzz. Do you think it would help to raise the nut so that when I fret a note it would have more tension? I don't think it's a high fret problem, it buzzes on all of them, & the buzz seems to be coming from the next fret in front of the note I'm playing, so if I'm fretting a D on the 3rd fret, it buzzes on the 4th fret, ect.
Edwin, you are not weird, I also don't like very light high strings & also prefer smaller low strings. I like a full punchy sound on all the strings so it sounds like a bass, not a guitar.
I absolutely love this bass! As a 4 string it is the best bass I have ever played, so if I can tame the B & get it to sound & play consistent with the other 4 strings, I will be in bass Heaven!
