So I have two basses that I really, really like. I have a Warwick FNA Jazzman and a Spector Legend 5. I have worked and tweaked them so I get a sound I like out of both. BUT, the Spector with the Tonepump is just SO much hotter than the Warwick. When I only use one bass this is fine, the volume is there for a reason. But I have a performance coming up that I want to use both my basses for. So the question is, in a live setting how do you go about normalizing the output volumes across more than one bass with noticably different output levels?
