eq's bang in the middle and like theledge said dont pump it at all.
use a transparent eq for little touches but ONLY if you need to (ie: old vinyl thats lost some thump) - but you really need to know exactly what you're doing with the eq.
the aim is to get a degraded vinyl back to as close to the original recording as possible.. not to add anything to it.
hence a good quality transparent eq (one that doesnt impart its own sound/tone on the recording)
