What kind of setups do people use to solve this problem? I'm in TWO bands that expect me to quickly switch from upright to electric in between songs. (I actually think that's cool, too - don't get me wrong... but it makes things technically complex.) I need to be able to just set one instrument on its stand, push a button or two, pick up the other one and go. I've been considering what equipment to buy and in what combination to hook things up to make it simple and not overly expensive. It seems like the problem is that the URB w/ Fishman Full Circle (piezo pickups) gets hit by an impedance mismatch when inserted into some devices (like my Mackie mini mixer). So it can't go there first. Currently, I've cobbled together a setup which works like this: I use a Mackie DFX-6 mixer which lets me switch between basses, and also acts as a preamp for my electric. The mixer has mute buttons on each channel which lets me set the volumes, and then turn on which ever bass I want. It also has individual stereo main faders which let me send different levels to the house PA and my rig. I plug my electric (with active pickups) directly into channel 1 on the mixer. I plug my URB into a Sansamp rackmount pre, and then its output goes into channel two. Left main output goes to my "rig", which is a power amp and a bass cab. Right main output goes to the house PA. So the benefits are - I get my volumes equalized for both basses, can adjust the house volume independently of my amps, and can "save and store" the settings for each bass. I can also easily turn both off during breaks. The disadvantages are that I'm schlepping a lot of stuff to gigs! What kind of solutions are others using?
