Played a trio gig tonight in the usual club after having also played one there last night. Last night, the weather was dry and clear, and playing the bass felt like the easiest thing in the world - action felt comfortable, the sound was strong and clear, everything was great. Tonight when I played, my bass felt like it was strung with steel bridge cables, and the sound was muddy hell....I'm wondering how much the weather could have had to do with that, and how much was just me? It has been raining all day, and I had a gig like this last year on a rainy night, and the same thing happened. So what's really going on with the bass when it gets humid? Do the strings actually get higher or lower? The strings on my bass felt like they had about twice as much tension as usual tonight. Do barometric pressure changes also affect the bass, and if so, how? Does high humidity always make the sound muddy, or is it more complicated than that? Any and all replies welcome.
