500 iw a good frequency. My fav eq points are
Hi pass filter, 80, 250, 500, 1200, 3000.
The issue with my bass is there is a TON of low mids bur very little 600 and up. I can eq it up, but the overtones and harmonics still sound dull and some even missing. So I have no problem making the bass sound brighter, but whenever I do, it still doesn't sound good. I like those upper mids to be well balanced, almost equal (to the ear) with the low mids and lows.
You just can't eq up something that isn't there and THAT is my issue with this particular instrument. If the upper harmonics were present and clear, I wouldn't care that It needs eq. But the bass seems to just naturally kill them off. Not all mind you. There are "some" upper mid and high harmonics, but they are missing a good portion of them.
When I get off work, I'll post a clip of the bass with no eq at all. It will be a lot easier for you guys to hear what I'm talking about over me trying to explain it.
