Dear Sirs

Thank you for your inquiry.

The products provided in our Rosewell package from Teisco pickups are the GF-3H and GBR models.
The GF-3H model is structured as a single bobbin pickup, but in terms of the NECK pickup,
weak "S" polarity magnetic force is emitted from the screw part, while strong "N" polarity magnetic force is applied on the wider surface.
Therefore, if the pickups are arranged in the same direction, the effect of single coil strat configuration can be expected.

For the GBR model, only one polarity is applied, so you may feel a different tone.

The crucial point here is to ensure whether the output levels of various types of pickups being installed,
specifically whether the output frequency values are in the plus or minus direction, to eliminate PHASE OUT (sound attenuation) phenomenon.
The best solution when this issue arises is to try reversing the wires connected to the output.

If you have any questions, don’t hesitate to let us know.

Best regards,
paul – Production manager
