Re: S5470 bridge swap - sustain issue gone
This is very useful to know actually.
For me, while the ZR bridges have rock solid tuning stability and are quite ergonomic - it was always evident to me that they sap so much tone. I think this is also true of the SynchroniZR too as my SV5470 doesn't ring out as true as my Lo-Pro Edge Sabres. Thank goodness the ZR line has been replaced with the Lo-Pro Edge.
Out of interest, did you have to mod the guitar much or was is a simply direct swap? Do the Edge Zero posts drop right in to the ZR threads?
