After removing the Greasebucket Circuit and having some truble with the neck PU on my Highway One - which I could luckily fix - I wonder if upgrading to CS '60s would be worthy. Did anyone compare the stockers to the CS? The stockers are nor standards either American standards. They're advertised as "Standard Vintage Alnico Magnet Jazz Bass Single-Coil Pickups" Soundclips would be helpful. I've did a lot of research, but couln't find any.
