Quick Garageband question

Ok, so i bought the hookup so i could record bass and guitar into my Imac (G5) but it only seems to record in mono... did i buy the wrong thing? or does it only record mono?

How could a bass or a guitar possibly give you a stereo signal?!

Yeah. What you need to do is insert your bass/guitar recording in both L and R tracks, this has nothing to do with the hardware...

Though i don't think garageband uses left/right tracks by default in the first place...does it?

ok so how do i get it to become stereo, record it once and throw it to the left channel then duplicate and go to the right channel?

when you add a real instrument in garageband in the advanced options you can select which side its coming in on - i think it defaults to both Left and Right ie a stereo input, but if you select just the left channel it will reproduce the signal in both sides ... hope that makes sense - don't have my ibook at hand to check
