I have always bought into the 35" scale is the way to go for a nice tight, focused B string. So, consequently I own 3 Lakland 5 string basses and a Mike Lull 5 string. All with 35" scale. And they do, indeed, have a great B string. However, I also own a Fender American Deluxe Jazz V, Gibson Thunderbird V, Squier VM Precision 5, all with 34" scale and a great B string. The proof is in the pudding and dependent and each individual instrument. Although I will say, I have owned 3 Fender American Deluxes that have had good, solid B strings. 34 or 35? get what sounds best to you!
