More neck bow (though you've tried that), raise the bridge saddles, use more neck pickup than bridge pickup, roll the tone back, roll off some upper mids at the amp.
Though some fretless basses get much more mwah than others.

Hi Hugh,
Actually I posted a bit prematurely. I only did the truss relaxation shortly before posting. I tried the bass again this morning and the mwahh is now much more manageable. So, I'm a lot happier now. Thanks Hugh and thanks to all others, even the silly answers too,
Cheers
Rich
