I almost wanna downsize, but I'm too indecisive. I "gave" one of my old Music Man basses to my youngest son. I have a Talkbass ad up to maybe sell one of the other two. I am not, however, a motivated seller. If somebody meets my price I'll sell one. But if not I have no problem keeping both.
My Alembic's are untouchable.... My Marchlewski is irreplaceable (Jake doesn't build anymore).
I do play a bit more 4-string in my current band, but I typically make certain I have a 5-string nearby. There are about half a dozen songs in our 45-song shows where I feel like I HAVE TO use a 5-string. The rest can be either 4 or 5-string.
