The Allparts Tremol-No is a patented device that is attached to an electric guitar equipped with a trimolo/vibrato unit. If you break a string or let the bass E to D tune, the other strings will stay tuned. Allows guitarists 3 playing options: Three in this position their three-molo works as normal. You can raise or lower the pitch of notes with the three-molo. -Trimolo off: In this position, you will enjoy the benefits of a hard-tail bridge, where the threesome does not move at all; without lowering or raising the tone of a note through the threesome, and the other strings stay in tune if you break one of them. - Threesome dive mode alone - in this Position, you can only lower the pitch of notes. Tremol-Not comes in 3 versions: Type 1 pin (sold on this page) is designed to work with three-molo blocks that do not have a flat base, such as those that are rounded or beveled (to allow more three-molo trips).
