ran the hpf on the v3 at 1 for the first set and then at 2 for the 2nd set. should ahve had it on 2 the whole time.
At setting 1 the rolloff is at a higher frequency which will result in less bass overall. But then you said that you prefer 2 (which has more bass), which implies you might want to add bass to the first set, but the thread was 'removing bass'.
Any chance you're confusing the settings or which set was recorded with which setting?
Also, do you know what your jumper settings were (slope and cutoff). If so, it will be relatively easy to mimic in software.
