Vintage 1970 Tempo (Shin-Ei) 6Tr Fuzz Wah – Collector Grade

A Pristine Piece of Vintage Fuzz History

Step back into 1970 with this museum-quality, all-original Tempo Fuzz Wah. Manufactured in Japan by the legendary Shin-Ei company, this pedal is a pristine example of golden-era effects. While it bears the rare "Tempo" export badge, under the hood it features Shin-Ei's distinct 6-transistor (6Tr) Fuzz Wah circuit.

The 6Tr Fuzz Tone

Unlike the aggressively loud, 8-transistor WF-8 models famous for their chaotic noise-rock capabilities, this 6Tr version allocates 4 transistors to the fuzz and 2 to the wah circuit. The result is a pedal that shares vintage Shin-Ei DNA but delivers a slightly milder, less "gnarly" fuzz tone. It provides a highly usable, classic 1970s fuzz saturation that interacts beautifully with the sweeping frequency of the built-in wah.

Unmatched Collector-Grade Condition

Finding a 50-plus-year-old Shin-Ei pedal in this condition is incredibly rare. The black crinkle-finish enclosure is virtually flawless, the brushed aluminum faceplate is exceptionally clean, and the chrome treadle shines brightly without the heavy pitting usually found on these models. The original Tempo badge is perfectly intact.

Under the Hood (Originality & Maintenance)

This pedal has been meticulously inspected. The internal circuitry is beautifully preserved and highly original.
