I'm looking for a solution (under $50) to combine a bass and a keybass into one output that will be sent to FOH. All while maintaining the signal quality (virtually no noise prefered). I'd be switching (being able to switch fast is also preferred) between both the bass and keybass, but not playing simultaneously. I plan on getting a di with an eq/comp, (GK Plex or Eden WTDI), and I would only like to route the bass guitar through the di/eq/comp. The keybass (novation Bass station 2), and at the end of the chain it would all be run into another di box. Unless I can get a box can balance the inputs. There are so many options, I hope this can help someone narrow it down with me.
