I'm looking to string a 6 string fretted bass in 4ths, low E to high F, with a fairly clear sound. I could buy a Pyramid 7 string stainless set and throw away the low B, or....what? One retailer has GHS Boomer 'High C' 5 strings sets, which I guess are E A D G C, which is fine, but what to use for the high F - any ideas or alternatives please? The exact sound character is less important than a decent sound with consistency across the set, particularly on the C and F.
