You are a guitarist, a bass guitarist. a 2nd or 3rd guitarist in the band. Dont pay any attention to people's ignorant comments. If you wish to hear or show someone exactly what a BASSIST does, listen to Allen Woody,from GOVT MULE. He is/was one of the best musicians ever. And 80% of listeners cant tell who is playing what,other than drums.or piano. Most cant look on stage and understand which is a bass or a guitar, . few know nothing more than half the chorus, and thats usually after the song is almost over. Anyone that matters will respect your efforts. SO........you just become the best bassist you can , and enjoy doing your thing. I think all ,young bass players have wrestled with the feeling,that they feel they gotta explain or justify,what their role is in the band. I started on a pedal steel guitar @ 14 yrs old. You cant imagine how many folks thought I was playing a little keyboard. and we didnt have a piano in the band. Tell them that your the one ,every other instrument is following. YOU ARE THE ONE THAT BRINGS THE THUNDER!!!!!!
