I made another song! This time it was just straight up recording a track on the drums, then playing guitar over it. Definitely doing significantly better in terms of staying in time now. 😛
For the guitar, I used my new Ibanez and switched it to the split between the bridge humbucker and the middle single coil, and it's SUCH a nice sparkly sound! I added some reverb after the fact in Logic Pro as well, since I don't have my reverb pedal yet, and man it's amazing how much of a difference it makes. The whole guitar just sounds more... open, I guess? It's hard to describe but it's quite a noticeable difference.
