I'm in a band that only recently started up, and we're on our third practice. So far we've just been working on one song, previously written by the guitarist, with this long form, post-rock, Explosions in the Sky kinda sound. We've discussed that we want the band to be more collaborative but because this is something the guitarist has already written he has a bass line already worked out for it. The problem is this: he "writes bass lines like a guitarist". It's very chord heavy, and while I've played around with double stops in the past, getting an even tone strumming all four strings has proven to be a challenge for me. A pick seems to be a necessity to play it, which I've also never really done before. After last practice he wrote out the tabs for me, so I'm making a little headway, but I feel I've been a bit of a drag on our rehearsals and honestly my poor technique sounds bad to my ears. I can easily play simplified versions of these lines, but it is his song and that's how he wants it to sound. So what would you do in this situation? Admit it's beyond my skill level and tap out? Just keep drilling it til I get it and push through some awkward rehearsals? Advocate for playing the simplified lines? Or are there any gear changes I could make to make this easier? I've had a little better luck with my Fender P with medium D'Addario Chromes, a thinner pick, and playing close to the fretboard, but I'm very much open to suggestions.
