Vintage 1960s Schaller Germany Bow Wow Yoy Yoy Guitar Effects Wah Pedal

I was recently walking through the streets of Copenhagen when I stumbled across a little store on a backstreet that had a pair of incredible one owner pedals from the 1960s. This being one of them - a Schaller Bow Wow Yoy Yoy. This is one of the earliest they made in West Germany, and is in wonderful condition and working order. I love the name of the original owner on the backplate (the same as the other I also purchased). Don't miss out! Please check out the pictures below as they form part of my description.
