Amplifier = Honesty
I finally got around to hooking up my bass amp to the game. OH MY! Now I know how much the game has been covering up for me. What a smack down to your ego. I'm glad I did it though because now I know how much improvement I need in being more exact with finger placement among other things.
If you want a reality check and have the equipment to do it, I highly recommend it.
I must be a bit of a masochist really.
