I have a Line 6 Pod 2.0 with GarageBand and Guitar Rig on my iMac. Going from the guitar to the Pod to GarageBand created too many amp/effect variables, so I went straight from my guitar into the computer's line-in. When using the programs' metal tones, I get a lot of feedback and latency. Could it be my line-in's fault, or just the fact that I'm recording with GarageBand like an indie rock kid? I might be doing everything wrong... what is the way to go with my software/equipment, and how do you all record guitar?
