I cant find a specific pickup in your website.

i dont know its name but its like your 6-string fanned fret humbucker pickup
(https://roswellpickups.com/product/6-string-fanned-fret-humbucker-pickup-allen-pole/),

except its not a humbucker, its a single coil that goes in the middle.

I saw it a guitar with triple pickups on youtube and liked their sound and after some research i might be buying a similar setup.

This was the video i saw them on if it helps,
