well if u are really anal about music then u will definitely notice a big difference, because josh is in no way a jazz guitarist and there is no way he will be able to play those two licks clean on stage. so itll be different for sure. my buddy brandon played one of their songs by himself and he had a little bit of trouble just cuz its two guitars, however he has been playing for 10 years and is a 3rd year jazz guitar major in college lol.
