Thanks again!
I hadnt noticed the 760a was a j pup I was looking at buying one today for very reasonable dough, but I decided to go with a BB404 [ to a large extent because they are passive plus distance for collection]
I am playing a BC Rich Mockingbird Which I came accoss and bought ages ago when I wasnt really playing bass, thinking I'd get back into it again at some point, Which I now have! I had tried a custom built one 30years ago when I was in a band and it had always stayed with me how much easier to play it was than whatever I was playing at the time. I hadn't even heard of P and Jazz then. I dont understand what the hell is going on with the controll nobs and setting up the sound is always a bit random and unsatisfactory. I think I would prefer a passive with nobs I understand! The way the B C Rich hangs down is unpleasant too.
TBH Im not that good and still looking to find 'my sound' I am now thinking Maybe buying two bases, P and J, and experimenting with both for a while might be the way forward. So 2 Yamahas would be afordable and hopefully help towards both bases of a similar quality so as not to confuse the experiment.
Many thanks
