Soo after checking out the Joly mod for the bluebird and fiddling around with my previous BB. I decided to save a couple bucks and do half of the mod myself. I didn't change the capsule or any of the electronics. this is a very simple and reversible modification. I just unscrewed the basket and flipped the capsule over to the round side and removed the internal mesh that was causing some standing waves.
anyway. first half is modded, second half is stock. you can hear it more in the right channel.
