Thanks for the suggestions.
I use a Spector Legend and Rex4 as well as a P with hot DiMarzios and I can cope with changes live with no messing at all with my amp.
I so want to love this bass, I'm sure it's the pickup height that is the major problem.
There's thread after thread regarding this 'issue' on the bassesbyleo forum dating back years.
I'm going to spend another few hours setting it up again, reset to the settings in the manual and start again.
I've got to find the sweet spot!
I ran it passive/parallel and at about half volume at one gig and it was a passable P tone. I Iove the series thump but, it was too much, too boomy - whic,h to me, points at the pups again. I do give it some when I play with a 'Steve Harris Style' though - it's just a totally different beast to anything I've ever played before!
I'll stick with it for now and report back!
Thanks again guys, it is really appreciated and I take no offence to any of the comments . . . So far!! ;-D
