I just bought my first guitar with a Floyd Rose system and I absolutely love it. Now when I tuned it all up, and do some dives with the bar, and let it come back, my strings are all de-tuned a small bit down. Some more then other. My low E string de-tunes like a quarter step down, other strings maybe a few cents. When I pull the tremelo bar again, in any direction, it tunes back perfectly.
The strings have just been replaced with Ernie Ball Super Slinky's (09 - 42).
What could be causing this? Could this be a defect or is this a matter of setting up the guitar? It's a Charvel San Dimas guitar equipped with a "Floyd Rose® 1000 Series".
