Andreas’s deep dive into pickup data involves a remarkably intricate process: he carefully unwinds old, vintage pickups, a meticulous task that can take up to two days. This isn't just about counting windings; it’s about understanding the exact tension, pattern, and unique nuances of how the wire was originally applied to the coil. He has painstakingly analyzed countless classic pickups, from legendary Gibson PAF Humbuckers to revered vintage Strat pickups, discerning their unique characteristics and sonic signatures.

What truly sets Kloppmann pickups apart is the method of winding, precisely tailored to faithfully recreate the nuances of the originals:

• For Gibson-Style Humbuckers: To precisely replicate the iconic, warm tones of the late 1950s, Andreas utilizes historic Meteor M301 Winders. These exceptional Swiss-made machines are the very same models used by Gibson starting around 1959. This ensures an authentically period-correct winding that is crucial for capturing the soul of those legendary humbuckers.
• For Most Fender-Style Pickups (e.g., Early Strat & Telecaster): The vast majority of these classic designs are still individually hand-wound. This traditional method, often guided by hand on an old Siemens winding machine from the 1960s, is paramount for achieving that unmistakable, lively vintage Fender feel and incredibly responsive output.
• For Later Fender-Style Pickups (e.g., Strat '65 & '67): Reflecting the evolution of manufacturing in the mid-1960s, designs like the Kloppmann ST Real 65 and the ST67 sets are wound on a vintage Aumann automatic winder (Made in Germany). This choice perfectly mirrors the automated winding techniques adopted by Fender during that specific era, ensuring absolute sonic accuracy for those distinct designs.

Andreas’s extensive experience allows him to finely alter winding parameters during production, precisely influencing the pickup's final sound. He maintains an invaluable database of frequency response diagrams from various manufacturers’ pickups dating all the way back to the 1950s. This comprehensive resource enables him to compare and match original specifications with incredible accuracy, ensuring every Kloppmann pickup is a faithful recreation.

Every Kloppmann pickup bears a unique character and a dedicated production number, allowing Andreas to re-access its specific frequency response data. This detailed data can even be provided to customers for comparative analysis, offering an unparalleled level of transparency. For those who prefer to rely on their ears as much as data, Andreas is also an accomplished performing artist with 25 years of experience, a renowned vintage guitar specialist, and rigorously benchmarks all his products by critical listening.
