The Regular Slinky will feel in tension like you tuned your bass up a little more than a half step.
Ok, so I have used D'Addario XL Nickels (.045 - .105) for as long as I've been playing, and i'm considering switching over to some Roto Swing 66's in the near future. I'm thinking of going with Medium (.040-.095) or Med-Light (.035-.90 for a change. Will there be an extreme difference in tension? My Carvin has tension adjustment but I'd rather not have to use it.
