Hey there Talkbassers, I was wondering if anyone had some set up advice for doubling electric and upright bass. I have an Aguilar tone hammer 500 and 2 sl112s and love the set up but what would be a good way to have both basses set up for a gig without a lot of unplugging and changing eq settings? Can I run a dedicated preamp for my upright through the effects return and just leave my upright plugged in?
