By Inventor Davide Bissoli here is a new tremolo stopper for guitar setup and repair.
The FRET GUARDIAN is simple and powerful. It engages with the springs pocket and with the tremolo block, quicly and precisely.
Its use is simple. It must be placed in the pocket close to the block and in between the springs. If there isn't enough space a spring can be moved aside or pulled. While the tremolo is kept in position the two middle nuts (weels) are turned to reach the tremolo block frontally and behind. Then you are ready for restringing, intonation adjustment and all those operations that require your tremolo to be stady and stable. It can be used also while recording to improve intonation for perfect pitch arpeggios and rhythm guitars.
