Putting a mastery on a mustang is pointless cause the strings don't slip or buzz and the strings have a short and sharp break angle from bridge to vibrato,like a gibson LP does which results in no buzz etc.. The mastery was primarily designed for jazzmasters and jaguars.
And I agree with fran about them. To add to this, Sonic Youth probably get them for free or at least dirt cheap and just because SY use something doesn't make it perfect for everything. IMO the stock mustang bridge is perfect (well not perfect but close) for the mustang and a TOM is just as good if you like narrower string spacing like me.
The mastery has been classed as "the perfect bridge" by a lot of rich folk but it has at least one design flaw, you
CANNOT innonate some (a sht load of) alternate tunings, its actually physically impossible to intonate my tunings on a mastery (and I dont need to buy one to know this,its an obvious observation) as mastery's only have two pivoting saddles. I can guarantee you that at least half of SY's guitars aren't intonated properly either, the ones with mastery's I mean. SY's guitars would have at least 1-2 strings that the intonation is way out because you cant move JUST THAT STRINGS saddle back or forth on a mastery like you can on a mustang and TOM bridge.
Its almost as bad as them PRS wraparound bridges,if you dont play 9-42 strings in EADGBE they wont intonate 100%.
To me its an over priced bridge with flaws. Just like the fender ones, they are all slightly flawed. If you want to stop the mustang bridge rocking just wrap tape or aluminum foil around it, problem solved. Or use a Gotoh TOM for $30. IMO the Mustang bridge has less flaws than the mastery because you can intonate ANY tuning ona mustang bridge, where as mastery's are really only good for standard tunings.
If this thread was about a jazzmaster or jaguar it would make some sense but a mastery on a mustang makes no sense whatsoever.
