Here’s a track I recorded using just the Seymour Duncan SSL-5 single coil for 7-string in my Ibanez UV777BK Universe. The SSL-5 is a high output true single-coil for warm instruments, with Alnico 5 rods and a DC Resistance of 12.9k. Though it looks like the SSL-1 and has that distinct vintage tone, the SSL-5’s over-wound coil yields higher output, more sustain and great harmonics. The result is a pickup that rocks hard and cuts through the mix, but cleans up nicely when you back off the volume. The other pickups in this guitar are my Custom Shop Magnetar and a Production Floor Custom Sentient with white logo and glossy bobbins, but I don’t use those at all in this track: everything you hear is SSL-5.
