S8 String Through Pickup
The S8 (S for Split Coil) is a humbucking split coil pickup that utilizes a magnetic yoke arrangement, as used on multiple classic string through pickups. The magnets connect to upper and lower steel plates creating a uniform magnetic field in the string zone, which allows for free string movement since there is no net magnetic force on the strings.
The neodymium magnets were carefully selected to provide a field strength in the range of the most famous string through pickup, and adjustable 10-32 pole pieces are provided for precise string balance.
The window for the strings to pass through is ¼ inch tall, and the design intent is that the strings sit in the middle of this height at about 1/8 inch or slightly more above the lower edge of the window and the pickup pole pieces. The top surface of the pickup is about ¼ inch above the strings when adjusted in this manner. The S8 usually requires a rout depth of at least 3/4 inch on a typical installation, see pics for an illustration of this.
The S8 is supplied with a custom 3D printed flat mount ring for lap steel applications. The pickup is also supplied with mounting screws and springs for correct placement of the pickup on lap steels where the strings are 1/2 inch above the body, other heights can be accommodated with longer screws and spacers, contact us for details.
Other pole spacings are available on a custom basis, contact us for details.
String through pickups do create a bit of a challenge for hand placement and string damping, but the area and height of the pickup body was minimized to the extent possible and the top surface radiused so the right hand can move smoothly from in front of the pickup to resting on top to picking on the fretboard side of the pickup body and damping with the back of the hand on the bridge side of the pickup body.
The payoff is the string through design and the uniform magnetic field completely surrounding the string gives great clarity of tone, and the upper harmonics of the string really ring out.
Here is a sound file I put together to demonstrate the S6 and S8.
