Hiya folks, Well, I'm in the process of finishing and setting up a bass for bluegrass, and currently considering what to string it with. I'm looking for opinions on how well Kolstein's new Heritage strings would fit the bill for this bass, not having an opportunity to try them myself as of yet. The goal is to go with something that's somewhere between the plain gut vs. Spirocore ends of the spectrum (which could mean just about ANY string, really... ), but leans toward the latter i.e., has a solid fundamental, good volume and decent sustain, yet is a touch warmer/darker than Spiros. Another consideration is longevity; as much as I love the tone and feel of a fresh set of Oblis, for example, I've experienced some of the same issues as some of you have with them simply not lasting. Given the relative newness of the Heritagesesess, can anyone yet really speak to how they hold up long-term? Regardless, from what I've read on the boards, it sounds like the Kolsteins might be the ticket... Opinions? Any bluegrass players out there already using them? Thanks as always for the input, guys.
