The Aloha Twin can be installed two ways:

1. With the supplied double-sided adhesive tape in front of the bridge plate (or bridge, if no bridge plate is present) on the inside sound board.
2. With superglue on a flat bridge plate (or directly under the bridge, if no bridge plate is present). Please note that the bridge plate must be completely flat - it will not work if the bridge plate is radiused, which means it is curved up, e.g. Mele Ukuleles.
