Changing from 11s to 10s will make spring tension greater than string tension to start with so your trem will tilt back.You can keep the 5 springs and loosening springtension with the springclaw til spring and string tension is equal and tremolo floats parallel with body.I removed one spring because I felt it was abit too stiff with 5 springs when I changed to 10s on my DGT.I still had to adjust the equal tension of the springs and strings.Final adjustment you have to do is intonation.I'm going to post about changing to 10s. If anyone knows what the process of changing strings to 10s please post. Thanks.
