Installing a hex pickup is just like installing a regular pickup, except instead of one positive and one ground wire, you have six positive wires and one ground wire. The wires are color-coded, and go in this order, from high to low: white, black, red, green, yellow, blue. If you reverse the orientation of the pickup, it will still work but the order will be reversed. The six positive wires each go to a pin on the 7 pin output jack (included free with purchase of a pickup and breakout box) and the ground wire connects to the ground terminal of that jack. One pin is left over (I remove this pin before shipping, to avoid mistakes):

For 13 pin output jacks, the pinout is as follows: high e: pin 1; B: pin 2; G: pin 3; D: pin 4; A: pin 5; low E: pin 6. Pin 7 can be used for the remaining stock mono pickup(s). 13 pin DIN panel mount jacks, as in the picture above, are available for $10 each.

Other options are possible, such as adding a switch that combines the signals to mono, or to different stereo configurations, or adding volume and/or tone controls.

They go in this order: white black red green yellow blue. Which direction depends on how you orient the pickup. It should be fairly easy to tell which side is which by looking at the wires where they enter the pickup.

Standard coils have a DC resistance of around 7.5K ohms. Plus coils have a DC resistance of around 3K ohms, but are more powerful than standard.

See image below for the amount of cross-talk (bleed) between strings:

I will ship anywhere in the world. To date, Ubertar hexaphonic pickups have been sold to:

Argentina, Australia, Belgium, Brazil, Canada, China, Czech Republic, Denmark, England, Estonia, Finland, France, Germany, Greece, Hong Kong, Hungary, Iceland, India, Ireland, Israel, Italy, Japan, Latvia, Lithuania, Malaysia, the Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Russia, Singapore, South Africa, Spain, Sweden, USA

Yes.

For best results, install the pickup in bridge position, and adjust the pickup height so the pickup is as close to the strings as possible. They may not be compatible with all older models.

Yes.

I also carry sound-hole adapters so you can mount the pickup on the instrument with no permanent modifications to the instrument. You'll still need to put the jack somewhere, though. If you're a sit-down player, you may want to remove the strap peg on the butt of the instrument, and use the remaining hole for the jack.

You'll need to use strings designed for use with electromagnetic pickups. Examples of these are GHS White Bronze, and John Pearse 960L.

For nylon-string (classical) use Thomastik-Infeld KF-110 Classic S-series. These sound great and stay in tune much better than most classical strings, and they work with electromagnetic pickups!

Adjust the height of the pickup so it is as close to the strings as possible.
