i play a knutson messenger bass with helicore pizz strings (light gauge). i like them pretty well, and they sound even over most of the bass, but when i play the D on the g string in the thumb position (or any note higher) you cant hear it at all while the band is playing. in the practice room there's not much difference because i'm right on top of the speaker. why is this happening? i'm thinking that even though they're light strings they still feel kind of stiff on my bass and maybe since i'm stopping the string so high and the string length is so short at that point then maybe there's not enough ampitude to the string so therefore no volume. should i try a lighter string? i do alot of playing in that range so this is very important to me.
