Thanks all for the suggestions, just to reiterate, £1500 was an absolute max, I'll consider anything up to that amount.
Missed out on the marcus miller jazz. After a bit more research I stumbled upon the Modern Player Jazz series, seems like a viable option, skinny neck, will provide a different sound to the P (and thick and heavy due to humbuckers!), passive (forgot to mention I prefer passive, my pedals provide quite a high output with a lovely deep sound so active pups would be a bit too much).
Any thoughts on this series?
Or other suggestions, keep them coming!
