Buy High Pass Filter or KAB RF1?


Is a $25 high pass filter as effective for rumble as the $180 KAB RF1?

I would rather spend the lesser amount. Thanks!

My preamp has both a tape loop and processor loop.  I run it through the processor loop.

Good call, had forgotten about those.  It's cheap enough, I would give it a try.
So I called the company and the guy said the $22 passive version is pretty much just a high pass filter and would technically make an audible difference. He said they have an active product around the same price as the KAB now where you can’t hear the difference when using it.
