RARE Vintage 1974 Maxon PU-103 Wide Range Humbuckers – Original Greco TE-500 LOADED Pickguard + Electronics (Seth Lover Fender Thinline Deluxe WRHB)

A RARE 1974 Maxon PU-103 Wide Range Humbucker set — and not just any pair.

These are prototype units from the early Maxon production line, the very first attempts to reverse-engineer Seth Lover’s legendary Wide Range design for Fender.

Serial 14220, dated February 20, 1974, Maxon Pat. Pend.

What makes them extra special?

☑️ The Greco-embossed covers — only produced during 1974.

☑️ Prototype serial (starting with “1”), marking these as test-run units before full production began.

☑️ Original Greco TE-500 pickguard included — straight from the golden lawsuit era of Japanese craftsmanship, when Greco guitars were giving Fender a real headache across the Pacific.

Professionally checked & approved by Gerard at Tonespinner, these pickups are ready for decades of tone and inspiration. The wiring isn’t connected, so you can drop them straight into your dream build and wire them up as you please
