I play bass with fingers and have recently been given a set list for a gig I'm going to be standing in on. The band consists of acoustic guitarist, two vocalists, drums and bass. Now a lot of the bass line is primarily root notes, turnarounds an following the chords and really lush vocals nothing fast or complex but really well written and played songs. Now that I've started learning these songs i've noticed quite a difference in tone and attack between my first three plucking fingers on my right hand. Index finger has a stronger attack and a brighter tone even when played softly and the other two are mellow with less of an attack so when playing slow passages it's very noticeable if I play using alternate fingers. I've started using my 2nd and 3rd finger to keep the attack down on more mellow parts but I don't have the same dexterity with those fingers as with the 1st two. I'm presuming the difference is due to the hard skin on my fingertips and it's probably harder on the index finger because I also play guitar with a picks so probably become harder over the years from holding and playing with that between my finger and thumb. I could be wrong, and maybe someone can correct me on that thought. Any suggestions on how to even the tone and attack so that there is less of a difference between fingers will be greatly received. I have noticed this before but it has not been an issue before as the other things I play are, reggae so not much higher frequencies needed there or other genres where the notes are brighter anyway or move much quicker so it's not as up front there either. I do have a first rehearsal with the band this weekend and it may not be an issue for them and may not even hear it but on a personal level I'd like to know if i there is a way to even this out.
