haha good you noticed it! and yeah I wrote the whole thing in guitar pro, didn't play a single one of those instruments. I originally started recording the guitar and then realized how crappy my recording sounded, so I tabbed it out in guitar pro to get a sense of what it would sound like, and It sounded way better when I just exported the audio from guitar pro. However, for the next cover I do, I plan on actually recording the guitar and bass, and my drum set is an old simmons electronic drum set, which actually sound's worse than the guitarpro drums so I'll probably just stick with those drums.
