I'm kinda in a similar situation. I'm planning on buying a Schecter with fishman fluence modern pickups and I fear they won't work without the adapter, which is a no-go for me. I read somewhere about someone experiencing the same as you with fishmans.
The g10 works on both my emg equipped guitars and even my accoustic without the adapter.
I've read that it's a polarity issue and you can flip the wires on the output jack to make it work. I think this was on emg's though, but it might be worth trying. I really don't know, but I'd like to. :-)
