My black ice did have a very slight string buzz. This was even after I changed to Vapor Trail strings. I replaced the speed nock,shrink tubing and the factorystring jax.I repeat, that the buzz wasVERY slight.
I notice everything about a new bow trying to get used to it's personality.

I also put a MEANV suppressor on it and the buzz is gone and it added 5fps to the speed.I can barely tellI have released a shot.
Check the draw stop for tightness,and the limb bolt set screws,then take ALL your accessories off except the rest and shoot it.
Do you use a peep w/ tubing?
Is your cam timed properly within the tuning marks?

Keep us posted ,I curious to know the outcome. Your's is the first Black Ice to have any issues.
