As announced in May I have undertaken the task of modifying my favourite Ronaldo Custom and Fender P Bass.
I experienced very little difficulty in changing the bridge from a vintage style Wilkinson p bass bridge for Mexican made Fender P basses, the Hipshot Kicksass bridge designated as being a retro fit for that bridge type fit perfectly. I am a fan of the way that the new bridge allows to lower the action which was an issue with the Wilkinson bridge because of the larger saddles, the inserts for the Kickass Hipshot bridge made action adjustment much better.
The Tuners caused some issues, the stock licensed by Schaller tuners did not match the route for the hipshot tuners cited as the fit for the MIM fender P bass, but with some work it was able to be completed and not tuning issues have been had with the new hipshot tuners.
