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!![]()

Re: New Non-BOSS Pedals
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.

Re: New Non-BOSS Pedals
"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)!

That is a beast. Lovely old pedal!

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

Re: New Non-BOSS Pedals
Actually I have never heard of this song before. I discovered it while searching for more information about the Schaller wah. But it is for sure a cool song and the pedal adds a certain something.

New pedals in the house! I received a parcel by fuzzbuzzfuzz from Japan with a secret pedal that I am going to unwrap in a week. And it contained two Aria pedals and a rather obscure Pearl device.

The Pearl BC-21 Buffercord is not a device for guitar signals as I first thought. Instead it was used for the electronic drum pads that Pearl built in the '70s and '80s. These worked with piezo pickups and triggered sound devices like analogue and early digital drum synthesizers. This Buffercord transforms the impedance of the input signal so that the triggering works properly. I really might have a use for it in the future, because in the past I used the BOSS BP-1 Pad Controller (a drum pad with piezo pickup!) in combination with the inputs of my analogue synthesizers - and that only worked with a buffered pedal in the signal chain. This Pearl thingy could be a handy tool for exactly this application.
The Aria ADL-1 Analog Delay is a really nice sounding unit based around the MN3205. I have one already, a beat-up Ken Multi branded unit with a non-original battery lid. Now I have this nice looking original black version, even with the box and an old Aria pedal brochure. I really like the sound of it. Surprisingly clear sounding for an analogue delay. In stock mode it is very tame with little feedback. That's what I adjusted first. The maximum delay time isn't too long, even with the trimpot in maximum position. I wonder if a 1MΩ trimpot (instead of the 500kΩ) would allow for longer delay times. I might want to try that with my beat-up Ken Multi ...
The Aria ATO-1 Tube Overdrive is the sleeper pedal of the year! Our dear fuzzbuzzfuzz had one of these a while ago and praised it to the skies. For a good cause! He told me that it was a really decent transparent overdrive. Apparently it was introduced in 1993, at least this is the first year that I can find this certain model in the scanned Japanese Aria catalogues. Nobody knew the term "transparent overdrive" back then! This was one year before the Klon Centaur saw the light of day and also a few years before this certain pedal created a hype that defined the start of the boutique era. I have never played an original Klon Centaur, but this Aria Tube Overdrive is pretty much how I expect it to be. It doesn't get totally clean, though, but the breakup of the overdrive circuit is heavenly! Nothing in common with a Tubescreamer at all, just a lovely natural and "transparent" sounding overdrive with a very effective two-band tone control. It is easily among the Top-25 Overdrive Pedals that I have ever tried. Awesome!
The Aria ATO-1 Tube Overdrive was one of the latest additions in the pedal series (the last one was the AWH-1 Auto Wah in 1994) and I'm quite sure that not too many of these are around. Better make sure to grab one before some guys at YouTube start raving about them! If you see a Ken Multi MTO-7 Tube Driver, a Monarch MTO-22 or Pick Boy MTO-7 - these are all the same, just rebranded units.

Re: New Non-BOSS Pedals
Indeed glad you like them Pepe.
I have only seen two of the magic ATO-1 in Japan in all my years here, yours and one that went to a collector. I dearly wanted to hang on to one. It would be a wonderful unit to rehouse too with true bypass and a sturdier feeling case. Very neutral and lovely warm drive. A sleeper indeed….
