"The Pure Floating Bridge Pickup is designed especially for instruments with floating bridges. It features an extremely high output signal, warm and powerful sound, plus it is capable of extremely high volume without feedback!
The pickup is sandwiched between the feet of the floating bridge and the soundboard. This position allows the pickup to "hear" the soundboard as well as the bridge and strings in perfect balance.
If the jack is installed on the outside of the instrument, it can be installed with no (or minor) modifications to the bridge or instrument. If you prefer to install the pickup with an internally mounted jack, we recommend leaving this task to a professional.
With the outside mount, the jack is installed with the double-sided self-adhesive “dual-lock” fastener, which is factory-mounted to the jack (see photo). This adhesive will not harm glossy lacquered finishes. The glue residues can be removed with WD40. With un-lacquered finishes, we recommend applying some masking tape to the instrument first and then mounting the dual-lock to the masking tape. If possible, use the surface of the tailpiece or tailpiece holder.
The Pure Floating Bridge Pickup works well in passive mode. However, if a preamp is desired we recommend the Pure Preamp or the Pure XLR Preamp."
