User manual FISHMAN ARCHTOP GUITAR PICKUP

[. . . ] The FISHMAN ARCHTOP GUITAR PICKUP is a string-sensitive piezoelectric transducer. It comes implanted in the top of a complete replacement bridge. It senses string vibrations via two ceramic elements, located in the top of the bridge, directly above the height adjustment wheels. The ARCHTOP GUITAR PICKUP is a "passive" style ceramic pickup that can be used without an onboard preamp. [. . . ] FISHMAN TRANSDUCERS WILL NOT BE RESPONSIBLE FOR ANY DAMAGES TO YOUR INSTRUMENT.

At 10 M, the full frequency response of the instrument is reproduced. The ARCHTOP PICKUP can also be plugged into inputs as low as 1 M with adequate results. At 1 M, the bass frequencies will be slightly rolled off. INSTALLATION For optimum pickup performance: FIG. 1: ADJUSTER WHEEL WIRING OPTIONS We suggest routing the pickup wire in one of the following ways: 1. Remove the shielding cap from the jack and thread the pickup wire through it. Solder the signal wire from the pickup to the tip connection on the jack. Solder the shield from the pickup to the ground tab on the jack. If the instrument has a metal tailpiece, attach the supplied ground wire to it. If the instrument has a wooden tailpiece, attach the ground wire to the ball ends of the strings. ENDPIN JACK An E-Z mount endpin jack manufactured exclusively for Fishman by Switchcraft is available. A 15/32" hole must be drilled through the endblock and butt plate. If the instrument has a wooden tailpiece, attach the ground wire to the ball ends of the strings. STEREO WIRING IN CONJUNCTION WITH MAGNETIC PICKUPS. The Fishman Archtop pickup and magnetic pickup(s) can be routed through a stereo jack, fed through a stereo cable and mixed together via the Fishman Blender system. FIG. Fit the base of the bridge precisely to the top of the instrument. Note that the tops of the height adjustment wheels are specially beveled (See Fig. 1). Make sure that the beveled sides face up toward the top of the bridge. The adjustment wheels must be at least one turn (thread) up from the top of the base. [. . . ] Acoustic instrument amplifiers (such as the Fishman Acoustic Performer Pro) have a 10 M Piezo input; ideally matching the pickup. PLUGGING IN Due to the nature of passive pickups, the type of cable you use and the input you plug into will affect the quality of your sound. DIRECT BOXES You can plug the ARCHTOP PICKUP into an "active" direct box ( 1 - 10 M input ) with very good results. Using a passive direct box will sound weak and thin. INSTRUMENT CABLE Cable lengths over 10 feet (before preamp) will cause audible high frequency loss. Use a high quality, low capacitance shielded cable. This will insure minimal tone coloration and hum. [. . . ]
