VT Bass, Putnam-modified with headphone driver; want to practice with passive bass with music on iPod through headphones. 
So, how can I combine the line-out from the iPod with my passive bass signal into the VTBass so I can listen through headphones?
The reason for this is so that I can bring a minimal rig to practice with. If my description is inadequate, just let me know.
I may have to submit this under several different subjects until somebody both recognizes and understands what I am trying to do.
