Hi all, first post. I'm a guitard who also plays bass, and try to do it properly, but that's another thread.
I recently picked up a Yamaha BBT500H digital head on CL for $250 (I think it's a great deal), and noticed in the manual (p17 here
http://www.manualnguide.com/dl/443/ ) that there were clamp filters that supposedly cut down on EMI. You loop the cable through the clamp, and I've heard that there was a magnet in the clamp. I was wondering if anyone knew how to make one of these, maybe using a magnet and some tape? And if they did anything at all, as I've got some low level digital hash if I don't use the gate.
