The ‘61s are honestly probably my favorite pickup ever. If the ‘57s are anything like the 490s, go with the ‘61s. They may have Alnico Vs, but they are not overly bright and are still very articulate. Very well-balanced and capable of stuff that isn’t super heavy.
Here’s my amateur demo of a 2020 Epiphone LP Standard ‘60s, 2021 Gibson LP Standard ‘60s, and a 2020 Gibson LP Tribute.
