Bueno...después de hablar con un tio de Ibanez sobre el tema del puente me ha contestado lo siguiente:
“The Satriani models have a specific radius that is different from the normal trems.
This is rectified by small shimming plates underneath your saddles to raise the center ones to match the proper Radius.
Looking at the JS1200 there were 2 trems used over the years.
2004 – 2009 they had the Edge Pro (2EL1J21C with a 250mm Radius)
2009 – 2013 they had the Edge Trem (2ED1JS37C with a 270mm Radius)
So if you definitely have the Edge Pro you will want to maintain that 250mm radius.
In general though we don’t test these models for other bridges.
However I have provided you below with the measurements for each trem we have measurements for”
También me ha adjuntado las características de los dos puentes:
