Fastrack Usb Problem! Options

[andyg2412]

Hi, just bought a fastrack usb to make recording guitars much better for myself but hv
ave come across a bit of a problem!

I've got my guitar running in to the guitar port of the interface, but when i play back my recordings (through garageband on my macbook) it only plays through one headphone. The input volume level is also really quite low even with all the knobs turned up full.

Probably a silly problem with a simple answer, but I'm a novice and any help would be massively appriciated! Thanks
