Import / Record from SP-404 to Pro Tools with Mbox

Hey everybody! I'm new here, and I would appreciate any and all advice!

I'm trying to figure out the best way to record directly (FROM) the SP404 into a Pro Tools session in stereo (as far as hardware connections and track settings) - I have an MBox but I'm not sure if that will work? Thanks for the help!! I've tried using an AUX cable with an adapter, running it from the SP404 and into the first (guitar) input on the MBox, but the sound only comes in in Mono, and it's only coming through on the left speaker... I'm not much of a gearhead so I struggle with these kinds of things. : /

Sure! Thanks!

And as for the adapter... it's just a headphone adapter connected to a regular AUX cable on both ends... That might be a crazy thing to try but I'm still learning I'm sorry the images are so huge... Is there a way I can make them smaller from within the post?

Cable you need it single RCA -> mono 1/8. You'll need 2 of them.
That adapter and cable your using is wrong for the job.
I tell people this all the time Just because it fits, doesn't make it right.

You DREW A DIAGRAM for me!!! I cannot tell you how much I appreciate the help! I'll get everything set up properly and give it a whirl! Thank you so very much.
