For what is worth, the reamping fixed it. I recreated all the pedals using plugins. Adding 1.5k using the sd1 and dropping 3db of 500hz with a graphic was the ticket. The amp has a lot of 500, once that's gone the highs are there.
I also simulated the Naga using a high pass filter at ~2.6k and tried both adjusting the filter down and blending the unaffected signal in. I'm not quite sure if that's a 100% match of the circuit but it sounded the same. Its a cool sound and I think a Naga or clone like the PLX will work great.
+1.5k, -500hz using a graphic sounded best with the 'Naga' in a close 2nd, 3rd was a high shelf, and 4th was +1.5k, +8k on a 31 band. Haven't tested in the loop yet but I'm happy with it for now going in front of the od.
The tilt eq is sensitive to the center frequency. It does easily add brightness and is quite convenient but if the center is too high the range on the knob of acceptable frequencies gets really tiny so you can easily over / under shoot it when turning. This is the same problem with a parametric, if it has a wide range range of frequency coverage it could be hard to replicate your goldilocks zone on the pots. There is a difference between 500hz and 630hz tonewise so I think that's part of the reason I struggled to find the right combo with the ParaEq. The Tilt Boost could be really nice and easy for clean and overdriven tones or a leaner mix.
Gonna bring the laptop and reamp live next time but I think its the way to go to figure this out.
