I had three friends that I grew up with, that along with me, all three wanted to play guitar. We had just entered a big public high school ( after knowing each other from a small parochial school ) back in the late 70's, when garage bands were common, and started seeing that some of the cool long haired guys at this school, played in these bands. We then got to know a drummer, wich got us talking about learning to play ourselves, that's when everyone one of us said " I want to play guitar". So the friend that had the most knowledge and interest in this shared endeavor, said, "we can't all play guitar, someone will have to play bass." Without knowing much about the role of it, ( other than I liked the animated way Geezer Butler played in my favorite hard rock band, Black Sabbath )
I quickly said " I'll play bass".
It was the right choice for sure, even though early on, I learned to play it like a guitar...guitar riffs, and ignoring a lot of what the bass was actually doing in the song. One good thing about that approach was, often, what I was playing was more difficult ( at least physically anyway) to pull off, and prepared my abilities more quickly to play stuff like Iron Maiden later down the road.
Well, the friend that said " we can't all play guitar, someone will have to play bass", was the only one of the three that really stuck with it , and became a very good guitar player.
We "jammed" a lot for the next few years before getting into a hard rock band. That lasted for two years before a roughly fifteen year hiatus ( mixture of reasons )
but, so glad I picked it up again.
Here it is over forty years later, and I'm still learning the proper role, and the less is more discipline of playing bass along with a little guitar as well. I can say this, playing guitar inspires me to play my bass, more than playing my bass inspires me to play guitar = I made the right choice.
