Nice set-up.
I usually re-set my EQ every time I plug-in. I start with everything flat and start with my gain setting before moving on to EQ.
With my SWR350 I generally crank my input gain so it just barely clips. Try both with your head- Low gain with more output vol, and high gain with less output vol.
With the 350 head, try starting with the EQ flat and all boosts disengaged. If you have an active preamp, try starting with it set flat as well. How does it sound at this point to your ears in your current enviornment? It should sound pretty decent with the equipment you described. Step back from your rig and listen for unwanted reflections and try to pinpoint frequencies the could be cut. This is where the graphic comes in. Pop-in some CD's and try to mimic the bass tones with your rig. REALLY listen to how the bass is shaped so that it sits in the mix. This is where the 3-band comes in. Start with the mid frequencies and work with them before going on to your highs and lows. Finally, try engaging one or the other boost switches. Too much?? Quite possibly. But that's okay because the less circuitry the purer the signal.
Hope this helps,
