1970's Colorsound Chuck A Wah Original Vintage Sola Sound Effect Pedal

This listing is for a very rare 1970's Colorosound Chuck A Wah effect pedal. This pedal was made by Sola Sound in the UK in the early 1970's and is one of the rarest of the Sola Sound/Colorsound pedals. According to various online references this pedal is supposed to add a fat tone boost. The name is misleading and it's not really a Wah pedal. The pedal is a very subtle tone effect and is frankly an underwhelming effect. There is a slight tone difference when the pedal is engaged and the knob does almost nothing but as best I can tell this is just how they all we're made, at least according to what's written about them online.

The pedal would be a good one for collectors since this is very rare and possibly the circuit can be tweaked to get a more engaging effect sound but as I mentioned before, the effect sound is very minimal.

I posted internal pictures and as best we can tell the pedal is all original.

Please look at the pictures and message with questions.

Thanks for looking,..
