nordstrand will make any of there pickups in the 35 shape
so you can have big singles , splits, or dual coils all of them are suppossed to sound emmense
talk to a guy called brian at best bass gear for a price
either that or aaron armstrong Kents son will custom wind you a pair to your description of tone for a measly £75 per pickup
and they are also amazing
