Question harmonic balancer bad?

Ive got a bad vibration problem at exactly 2200 rpm (whole car shakes) and it doesnt matter if Im sitting still,clutch in our out, in every gear at any road speed Im getting this horrendous vibration.Only at 2200 rpm.

Ive had a few people check it out and all I ever hear is yes that they can feel it to but they cant figure it out either. The car runs awesome other than it feels like its shaking apart at that certain rpm. The balancer does look like it has a minor wobble but very slight. How can I check or diagnois this without buying a balancer first? Any help is app.

Thats possible but I just had the clutch replaced and the shop said it was fine. Can I check for that through the inspection cover?

If you can see wobble in the pulley, that's no good.
