So I ran across this band I had never heard of and decided to try listening to them. They are progressive metal and the trend is to have 8 string guitars and 6 string basses and drop tune them. Check out that shot at 0:41... his string looks like a wet noodle. Pretty cool bass lines and he manages to make it sound alright, but I couldn't help but laugh. Side note, I can't often tell the bass line from the low guitar part.
