I just went back to Fender 7150 pure nickel roundwounds (45-100) after playing DRs for a couple of years, and I have to say that I am in Phunky Phat heaven. These strings are a little higher tension, but with a little extra finger oomph, I get some tone! Anyone else dig these strings (or not)? For reference: I play a 1984 Jackson San Dimas custom shop Concert Bass (serial no. J0039) -- neck-through, dot rosewood fingerboard, EMG precision and guitar-style humbucker at the bridge. Poplar body. Pearl white (a cool color makes for better tone IMO).
