Warning
Not all PRS tremolo arms are designed for every PRS tremolo; some have a small variance in size that will affect its fit into the tremolo bushing.
Do not attempt to force a larger tremolo arm into a bridge with a smaller bushing. If damaged, the tremolo bushing can only be replaced by a trained guitar technician.
