Genz Benz 9.0 settings for Stingray?

Hi there. Got myself a nice new ray (standard 3 eq) but my genz is being a little temperamental in terms of finding tone. Up until now I've played an Ibanez ATK though this amp and it has been just fine with very little tweaking for different tones. For this bass though I am trying to get that 'ray' sizzle out of the amp and it's not playing ball at the moment. Everything comes out sounding a little flat, or in some cases too much treble, even with the mids and treb dialled down. I've been running the ray and all it's 3eq settings and nothing seems to do the job, however as soon as I play it through the gk rb amp at my bands practice venue it sounds like how a ray should, thick and grindy.

So, my q is, can any genz + stingray owners help me out here in terms of suggesting some settings that will work well with this bass?
