Hey, I have a Fender Rumble 60 Watt with two inputs, one passive and one active. I know that each one is for different types of pickups but I was wondering if I could hook up my bass and a keyboard at the same time. I'm sorry if its a dumb question I'm just curious.

Also I have a MXR bass pre-amp if that could help in the setup.

Thanks in ahead

I think you can as I've done it with a guitar amp and keyboard before, it will just sound utterly terrible.

Oh, it'll work. It won't sound great, though. Give it a shot, you won't break anything.
