I own both the Apex and the AT 2020.
They are both decent low cost mics.
I like the APEx a bit better for vocals.
Though neither of these mics are true vocal mics.
Better on instruments.
Actually my APEX was modded by Dave Thomas.
It sounds far better than the stock 415.
My friend has the stock 415, and it sounds not too bad.
Good for the money.
Also you should consider the CAD 2200.
Another decent low-priced mic.
