Advice re vocal settings

[Bertie59]

Hi
I've just invested in a new microphone  -  a Sennheiser  E835s and I'm trying to set it up on my s970 keyboard to use with vocal harmony.

I want a male voice to harmonise with my voice - that's not the problem really as I've purchased the vocal pack from Soundwonderlad  and the lower Unison voices which use the 'Mary to Bob ' settings on the keyboards vh section works quite well.

My problem is when the harmony button is off my voice sounds a bit thin.

I've tried the "vocodoubler " voice effect which helps but I don't know enough about EQ settings to know which knob to tweak and by how much to add more richness/warmth to my voice. 

Can anyone give me any pointers please ?
Thanks
Sue 😀
