Hey guys, I would love to hear what you all think about this. I am a 5 string player, and I have been for most of the time that I've played bass. when I joined my current band about 2 years ago, my guitarist played in drop Bb on a six string guitar. I suggested that he should get a 7 string and play in drop A, I told him that his strings wouldn't be as floppy and its only a half step lower. After rejecting this theory for months he finally decided to go with a 7 and we changed our tuning to drop A. Now hes tuning his low B down as far as he can. He claims he wants an 8 string, and to play in E. I keep trying to explain to him that I cant go that low. I keep telling him that the E he wants to go to is the lowest note on a four string bass. He keeps saying "play the octave" but then I wouldn't ever have any use for my B string, so I'd pretty much end up having to buy a four string. His upgrade will force me to downgrade. What do you guys think?
