I'm not sure any of us can answer that. I'll message Marcel and see if he can shed some light.Placed an order for a VF-5 in October and the Fbass made singles are no longer an option. Only the Aguilar's are available.
I've seen several posts in this thread regarding the tone of the Fbass single coils vs the Aguilar singles and HC singles, with no replies. I'm a bit curious as well. Aguilar offers a 60's and 70's wind, I'm curious if before they started using the Aguilars if the Fbass pups had a 60's or 70's wind, or did they use the same pups in VFs with 60's and 70's pup spacing.
