So, I just ordered a bass Trainer from Musician's Friend. I really hate blasting the stereo to hear bass parts to learn how to play them. Is this thing going to be a "life changing experience" or just a "gimmick"? I know the wife will appreciate me using headphones. It's amazing just how many producers bury the bass in the mix. Even with a really good sub (Velodyne HGS-10) I just can't hear what I need to hear. Any tips on how to use it would be very appreciated. Otter.
