Peep tube?? Do you mean the rubber tubing that lines up your peep when you draw? If so I would change that " variable" on your setup. That in itself is noisey and (although you don' t need it) it unnecessarily robs you of some speed.
Yea.......the tube is what I was talking about.
I took the tube off completely and it made no difference in sound so I put it back on. Maybe I will try a new peep with no tube.
