Floating Bridge String Changing Tool Durable plastic construction Soft pad on bottom side Tapered edge for easier insertion The TremBlock is designed to hold your floating tremolo system in a fixed position to allow for easier string changing. To use, simply raise the tremolo and insert the TremBlock underneath. Changing strings on your floating tremolo system can be tedious and difficult, but the TremBlock makes it simple. When ready to change strings, push the whammy bar down and insert the TremBlock under the bridge. The soft pad on the bottom rests on the guitar top, allowing easy access to locking hex screws on many floating bridge systems. Replace strings one at a time or all at once. Tune to pitch, then remove the TremBlock. This tool significantly reduces the time required for string changes on floating tremolo systems.
