I am prepping for gigs come May/June. Looking for two input and one output pedal/controller. Here's how I'm going to use it or why I need it. I will be using two different basses on stage --- yamaha bb1200S and Squier Bass VI. So want to be able to plug both into the rig; but be able to switch from A to B. Additionally, I know from practice that the I usually need to turn up the amp for the Squier when I practice, so the controller will need to be able to have output settings for each. I'm sure this device exists, but i don't know what to search for. Please advise. Thanks!
