I got my C13 toady, and it has a pulsating vibe. You can also see the vibe, it is coming from a pulsating wobble. It is not very big, but it is there. I already tried tuning it. What else can I do?
It’s probably your throw. Put your finger to it until it stops vibing… If it stops vibing, it’s your throw. If not, we’ll talk.
If its pulsing most likely its not his throw
Ever had a C13? Haha.
Oh, and you don’t have stacks on it do you?
No, I do not have stacks on it and no, it is not my throw. I held my finger to it and it still pulsated.
Some C13s tend to do that. Mine does it as well. Nothing to be worried about.
No I haven’t why are they notorious for pulsing?
Yeah, if you don’t have a pretty good throw, they tend to vibe just because of the imperfect throw. They’re beyond notorious for pulsing with stacks on though.
You might just have to move the axle around to tune it some.
Believe me, I have been tuning this thing all day, same result 
i tried 2 C13s and they had vibe
dont worry, be happy ;D
