I have a Mathews Switchback XT that has been recently making noise when I shoot it. I think it may be my drop away Trophy Taker rest but have not had problems in the past. Not sure what to do?? Will take all the advice I can get as I am frustrated.

tap on everything with your finger and just listen for it. Thats how I locate noise/vibrations

Ryan.

What kind of a noise is it? Is is before or after the shot?

like 7point said, start at the very bottom of the bottom cam, and tap your finger every inch up the bow (make sure to tap all over the cams, sometimes draw modules loosen). If that dont work, play with your rest, sight, make sure everything has no play in it.

Knowing only what I do about your situation.... my money would be on the vibration being in the sight. Have a buddy hold the bow and pluck the string like you were plucking a guitar string and listen... you should be able to isolate it that way.
