In my case, I have a Ricky with that floating bridge/tailpiece combo that makes adjusting the saddles impossible. So the upper register of my otherwise gorgeous instrument is a bit murky in the intonation area.
The tailpiece assembly is flaking, the foam mute is collapsed and the adjusting screws are gone, and the bridge saddles barely work as it is. I change strings 1 at a time on it because as long as I use the same gauge strings pretty consistently, it remains MOSTLY intonated correctly.
I would love to put a tailpiece that is designed to be adjustable on the Ricky. I also can kind of tell that guitars with the badass bridge on them (at least) are a little brighter.
Hipshot makes a direct replacement for the Ric bridge....prepare to rob at least 3 liquor stores to afford it.
