That’s truly wonderful piece of history and sound Pepe, and a marvellous job to bring it back to life! Great work. I’d love to hear a demo.Pepe wrote: ↑Thu Dec 11, 2025 1:18 amI acquired another vintage German Schaller pedal. Just like the fabulous TV66/67 Tonverzerrer fuzz pedal (that I bought almost exactly one year earlier) this wah seems to be from the earliest production months. So for sure a perfect cousin for the other unit!
This Schaller Bow-Wow Yoy-Yoy wah pedal was offered as defective and I won the ebay auction at a reasonable price. Many years ago the seller had removed the mode toggle switch as well as the original attached output cable and also the 3-pin DIN jack that originally served as a microphone input. He replaced the output cable for a standard jack next to the input jack. This was amateurishly done and the seller admitted that he had no idea anymore what he did back in the days.
Hadn't I been able to repair this pedal yesterday, I had posted this in the New (broken) pedal day! thread. I am happy and relieved that I can present it here instead!![]()

That’s a great size for what would usually be an always on utility device. Would sit nicely out of the way at the back of a crowded pedalboard. Nice score.Pepe wrote: ↑Sun May 04, 2025 7:32 pmAnd after a long time here is an addition to my Hotone Skyline series collection. The Hotone GATE is a very effective noise gate and very easy to use and just as all the other Skyline units it does a fantastic job. The possibility to cut the highs and the lows on demand is certainly a good option for some people. It was pretty cheap and it came with the box and the manual card, so I bought it on the fly despite having no urgent need for it.

"The most sampled African song in history" (according to Wikipedia), Soul Makossa by Manu Dibango (listen to it here), which was a minor US chart hit in 1972, prominently features the Schaller Bow-Wow Yoy-Yoy pedal in Yoy-Yoy mode right from the start (left channel).Pepe wrote: ↑Thu Dec 11, 2025 1:18 amIn Yoy-Yoy mode the pedal adds the second inductor which has a huge impact on the effect sound. It can be described as a crossover of a wah and a phaser. Very unusual and cool sounds are possible with it. And I think that I cannot achieve this sound with any of my other pedals. Another great reason to keep this rare beast!

Right now I have two 15µF Tantalum capacitors installed that replaced the original and rather odd 13µF capacitors. Later models have 10µF electrolytic capacitors. My model sounds way warmer than that recording. I am going to try single 10µF tantalum caps and then paired with 3.3µF in parallel to find out which value is the best one in my model.
This pedal is really awesome for such an early unit - the schematics are from October 1967, only eleven months after the world's first commercial wah pedal by Thomas Organ (Clyde McCoy)!

Soul Makossa is a favorite song of mine in it's original form, and in most every song that has sampled it, too.
