Opinions please....
I started in a band a couple years ago. Me on bass, a dude on guitar and his wife as singer. Another guitar and a drummer. Material includes Metallica, Soundgarden, Petty, Alice In Chains, Hendrix,,etc.... also originals....you get the idea. We played one gig during this time as rehearsal time is difficult and we replaced a drummer recently. Here's where it gets weird. A couple years ago when our pratctices were spread out by over a month each, the wife of the guitarist decided she should learn bass and start a girl band project. Well, that didn't go and so she started filling in when I couldn't make it. That's also how she writes her songs. Anyway, my conclusion is that while she likes to play bass, I am a bass player. I play the parts of the song she plays what she can. Much of the time I can't distinctly hear my part and its muddy.
Today I texted the main guitarist that perhaps we could decide on having me play the more difficult tunes and she could play on the easy ones. To me, the sound isn't crisp and tight it is muddy to have us both playing....even if improvise other parts that stay out of her way. Anyway, he said he didn't think that would work because she likes playing bass.
I think the band is cool and I have a bit of fun playing but think if they are ok with how she plays and are satisfied with her bass playing its time for me to bail.
