Lower pitched fly reel recorded with accurate high speed take ups. The fly reel manufacturer came in and attached a motor to the line to emulate the speeds and patterns in which a fish would take the line off the reel. The motor was in the room next door, so we are left with a pristine studio recording of the naked reel spinning exactly as if a fish was on the line. I'm pretty sure this has never been recorded in this manner before! The only way to get these sounds would be to record in the unpredictable and noisy "field".
