Ibanez Bridge Issues
I own a 2007 JEM7V-WH (Edge Pro) and a 2009 RG3550MZ (Edge Zero). I owned a 1527 (Edge Pro) in the past.
I've had the same issue with all 3 of them. After using the tremolo, the strings all either go sharp or flat. The bridge rarely returns to the original position (in tune).
I'm wondering if I've done something incorrectly setting up my guitars, if this is normal, or if maybe the springs just need to be stretched more.
I have a USA Jackson with an original Floyd Rose, and that thing has been absolutely rock solid since the day I bought it.
