This is, I’ve found, very common with bands I’ve played for or worked with, small and big, not bearing about the bass player nor their gear, but some exceptions have been quite the opposite and those bands always sound the better for it. Any group of selfish individuals who are only concerned with their own sound and not the blend of those sounds is not only going to be a drag to play with but a drag to listen to as well. The simple fact of the matter is that the bass is as vital as every other instrument and as ‘of course’ as that sounds it is a) rarely acknowledged, let alone applied in practice and b) rarely defended or even mentioned by us bass players while singers, guitarists and drummers ruin everything because of ego and intransigence.
I no longer have any truck with people who do not understand the democracy of sonics and I am incredibly lucky to play with people who don’t bring ego to the stage nor the rehearsal room. It’s a difficult balance to strike, especially when egos are involved but stand your ground Sir, you and your bass are as important as every other element of the band, don’t get pushed around because you are new or consider yourself lucky
