I changed strings yesterday. Cash flow being what it is, and the cost of strings being what it is, the strings I removed had been on the bass for 17 months. I didn't have a new set on hand so the strings I put on were the set that was previously on the bass and had been so for six months.
Things I found out. A set of strings that's been played everyday for six months sounds brand new compared to a set that's been played everyday for 17 months. Strings that are six months old have a lot more sustain than strings that are 17 months old. And, my house now smells like lemons.
I'm also having to re-EQ my rig, as I had been gradually making fine adjustments to my rig corresponding to the gradual deadening of the strings.
So, I learned stuff. And I think I need to order some new strings.
