The company
Before there was 369 WEIDNER, Armin Weidner developed electronics for others.
Since 1998, Armin Weidner has run his development office WEITECK Instruments in Töpen, under various company forms. He takes electronic products through every phase, from the first schematic to series production.
The WEITECK reference list includes companies such as Audi, Siemens, Bose, Harman Becker and Bang & Olufsen. The technology inside 369 WEIDNER today comes from this work in communications and audio electronics.

The product
Solfeggio Bad becomes 369 WEIDNER.
Solfeggio Bad has built a loyal customer base, sold at trade fairs, demonstrations and through referrals. Now it is getting a brand name that also works abroad.
The device combines a foot bath with electronic control: nine frequency programs from 174 to 963 hertz, powered by a 5-volt battery or a power bank, with more programs added by update. It is developed and produced in Germany.
The name comes from the digits of the frequencies 396, 639 and 963 hertz. Besides private customers, 369 WEIDNER is aimed at practices, yoga studios and wellness providers who want to offer the bath to their clients.

In his words
“With QvQ and BLUNATECH, for the first time I feel I have found exactly these people.”
“As an engineer, there is one thing you want above all: to develop good products. But a lot of what moves a company forward has to happen alongside that.
That is exactly why I have always wished for teams who take this work off my hands and think for themselves. With QvQ and BLUNATECH, for the first time I feel I have found exactly these people.
The start alone impressed me. How fast the work gets done here and how much expertise comes together is something I have never experienced like this before. What convinces me most is how long-term both teams think. This is exactly the kind of collaboration I have always wished for.
It frees my mind for development. I am really looking forward to the coming years with these teams.”
