I want to know if it is possible to get an EQ that is small and just does
higher frequencies. What I need is an EQ that will cut some digitial
artifacts and sizzle around the 7k through 10k range.

That is what nailed it on 31 band EQ I borrowed.

This is for simple direct recording into a PC, and if I do not attenuate
those frequencies the sound is HARSH, the that is where the sizzle seems to
be happening.

What are my options, other than buying a 31 band EQ of which I will use 2
sliders?
