Hi. So last week I put some new strings on my bass on Friday, had a gig on Sun. Spiro mittels on my Shen willow. I tuned them up a bit, a half tone maybe, and played them a little Fri. and Sat. hoping they'd stretch out just a bit by Sun. When I tuned them down on Sun. the bass didn't sound quite as good, especially my e string, a lot less punch. Can I do anything (short of playing out of tune) to get that sound back? Thanks, Tom
