I have a set of Nordstrand/Roscoe Dual Coils from a Roscoe Century Signature V. Like all Nordstrand Pickups, these sound really good and will open up the tone of your Roscoe. These are the P4 Dimensions 4.675" X 1.27". Roscoe string spacing is 18.3mm.
Will trade for a set of Aguilar DCB-6 D4 Size (P4 size) or Maybe a set of Bartolini Classics P4 size.
These Pickup sell for $315 new FS value $165 + $5 ConUS shipping, + $10 shipping for Canada, Hawaii or Alaska.
