Read Me First! Installation of this product is a straightforward procedure, but we recommend this job only if you are an experienced repair technician. Plugging In An impedance matching preamp is recommended, but not required. This will help realize the full frequency response potential of the pickup and allow for cable runs longer than 10 feet without signal deterioration. Use a high quality, low capacitance ¼” shielded instrument cable (models SBT-HP and SBT-E) or the provided cable (SBT-

Preparation The model SBT-C may be mounted onto a classical guitar, a steel string guitar, a dulcimer and similar stringed instruments. The installation may be performed either on the outside of the instrument or inside the soundhole where the transducer will be out of harm’s way. In instruments with small soundholes (dulcimers, for example), internal installation may not be practical. As a general rule, the transducer should be mounted over a freely vibrating location and STRAIN not over a

below the highest pitched string noting the position where these two measure- ments meet. This will serve as a test location. 2. Apply an adhesive pad to the shiny brass face of the transducer and mount at the location indicated in step 1. The transducer wire should follow the grain of the soundboard and point toward the soundhole of the instrument. Check the location by plugging in the pickup and listening. Should the position prove unsatisfactory, move the pickup in ¼” increments and re-tes

For additional information, please refer to the Switchjack Installation Guide located at fi shman.com. 2. Solder the pickup “hot” wire to the Tip terminal, which is the shortest of the three tabs. Solder the pickup shield to the Ground tab on the jack. Gently tighten the strain relief. Switch (Long Terminal) Ring (Medium Terminal) Guitar Tip (Short Terminal) Shield 8

Installing the Model SBT-HP The Model SBT-HP is designed for harp or piano. Parts � SBT-HP with 42” Cord and ¼” Jack � (3) Double-sided Adhesive Pads � Adhesive-backed Jack Holder As a general rule, the transducer should be mounted over a freely vibrating location and not over a “dead” structural brace. The exact location for best results should be determined by experimentation. For harp mounting 1 1. The approximate pickup position will be between ⁄ and ½ the soundboard’s 3 length, starting a

2. Apply an adhesive pad to the shiny brass face of the transducer and mount outside the instrument, at the location indicated in step 1. The transducer wire should follow the grain of the soundboard and point toward the bottom of the instrument. 3. Plug the pickup into an amplifi er and experiment with the vertical location of the transducer. If you detect boominess or feedback, relocate the transducer higher up on the soundboard. In no case should it be necessary to mount it higher than ½

For piano mounting The SBT-HP should be mounted to the piano soundboard at a location adjacent to the higher strings. For example, on a grand piano the transducer should be placed directly on the soundboard within the third-largest ranges of the piano. For additional instructions, see the above information for harp mounting. 11
