The definitive replacement tremolo springs! These are replacement guitar parts from RAW VINTAGE, a leading brand. Simply replacing your current springs with RVTS-1 will give you a thick, full-bodied tone with a vintage feel. The springs also add a unique resonance and improve sustain. ■ Tremolo springs are a very important part, and are key to the thick sound of 50-60s vintage Stratocasters. However, the springs currently in production have a strong tension and different characteristics from vintage-type springs. Raw Vintage thoroughly researched the tension of vintage-type springs and succeeded in developing springs with excellent torque feel and stable performance, while maintaining the same weight-to-size ratio. The increased weight compared to vintage types achieves a thicker sound. I installed these after purchase, but they weren't to my liking, so I removed them immediately and have been storing them. I think the condition is good. I sincerely apologize, but please refrain from price negotiations. Please consider purchasing at the listed price.
