I thought I would do some research on EQ plugins, to the best of my ability anyway. I use Logic Pro, Channel Eq and/or Linear Phase Eq....
I've followed this thread and downloaded a few EQ's
EQuality
DDMF Eq Pro
MEqualizer
I tried setting up a test with the same settings on each plug using one of my basses recorded.
Low Shelf cut at 145hz Q1.00 -6db
Boost at 1960Hz Q43 +3db
Both Logics plugs sounded the same, maybe there was a little more transient preservation in the Linear Phase plug but that could be my mind playing tricks.
The EQuality sounded similar perhaps a little fuller
DDMF Eq Pro and MEqualizer had less bass.
Then I realized that Logics and EQuality use the same Low Shelving curve whereas the MEqualizer and DDMF Eq Pro uses a Shelved Eq... meaning, it drops quicker to the desired frequency then levels off.
All Plugs have the Low Shelf setting but DDMF & MEqualizer actually have a Shelf Eq not a Low Shelf Eq. I would probably need to set them up differently to achieve a similar curve.
Not that all these plugs (accept for Logics) were indeed set up exactly the same, to my ears the Logic Plugs seem to have something going on in the lower mids I hadn't noticed before. It became noticeable when I heard the EQuality then went back to Logics. Logics sounded like it was coming down a pipe... if that makes sense to anyone... lol
I wanted to get in there and cut in the lower mids.
The EQuality sounded very nice indeed, whether its the curve used for the Low Shelf which rolls off the bass is a musical way. I don't know.
The MEqualizer and DDMF's didn't sound bad at all, just different somehow. The MEqualizer was very fiddley to get right, the soft saturation addition is a nice touch though and could be useful. I found DDMF least user friendly compared with the others.
Testing to continue this weekend to try and get all the curves right.

I have a hunch that these EQ's will sound very different in the upper frequencies. The bass was the best for me to try first as I been playing for over 30yrs.
What say you?
