Also recently, another good surprise for me was Curt Mangan flatwound bass strings. I tried some on a several-year-old Custom Shop Precision Bass and really dug them. Then I tried a second set on a handmade J of similar age that I was using to test sets of pickups. The Mangan flatwounds were great for J bass (I kept trying to cop old Bootsy Collins lines). When I decided I needed roundwounds on that J instead, for testing pickups, I swapped its Curt Mangan flatwound set onto a 1969 Precision Bass. Wow. With those strings on it, I heard that bass's voice completely for the first time. Expansive, open air surrounding thick, holographic low end. Huge. Pure, solid pitch. So nice. To quote Sarah Silverman, "So yeah... that's a good cheese."
