The Colorsound Supa Wah Fuzz Swell is one of the first multi effect pedals. Developed in the early 1970s in England, this pedal is hard to find today.
The huge and robust enclosure is definitively not pedalboard-friendly, but the design is typically for the 1970s.
The yellow metal footing is the base for a Wah Wah typical pedal with a rubber pad on top. The labeling on the front side is designed in the typical style of the 1970s and reminds of the blurred shaping of an LSD- trip image.
Such old Supa Wah Fuzz Swell pedals are so rare that even in the boundless vastness of the internet I was unable to find a circuit layout for this vintage cutie.
Besides two jacks for in- and output, the pedal has two footswitches.
And this is, where the Supa Wah Fuzz Swell becomes a multi effect pedal. You can create clean swell effects as well as fuzz or wah sounds.
Switched off, there will be a slight volume drop because the pedal does not provide true bypass.
The unit that found its way to my repair shop suggests that the Supa Wah Fuzz Swell initially had some rubber strips on the bottom to keep it from slipping. But these, as well as the screws of the bottom plate and maybe a battery holder got lost through the years.
In contrast to other wah pedals, the footswitches are not activated by pressing the pedal down. There are holes in the pedal instead, through which the switches are activated. In this case, it is wonderful to see that the manufacturer paid much attention to details. The rearward switch is mounted slightly angled. Thereby, it will be pressed down straight and will life much longer.
Colorsound /Solar Sound pedals has been handmade by Macaris in London. This music store is still a family-owned company and for guitarists and pedalfreaks it is worth a visit. Even today Colorsound pedals are produced there.
The Fuzz sound is based on silicon transistors and is oriented to the Colorsound Supa Fuzz.
Besides the wah pedal you will have to go without any further setting options but who needs them regarding the vintage correct sound.
A trim pot on the circuit board controls the volume of the fuzz and the maximum volume of the swell effect. By this, you can use the pedal as a booster as well if you adjust it the right way.
The vintage fuzz sound is really unique.
Similar to other wah pedals, the wah effect is created by an inductor.
However, what to me is pretty interesting, is the stereo pot which uses, depending on the chosen effect (wah/swell/fuzz) a separate range.
In contrast to Dunlop wahs, the pot is not controlled via a rack. It is rather comparable to a crankshaft which ought to treat the pot much more gently as the mechanism of the competitors by Vox or Dunlop.
For sure, this is the reason why the pot of this old device is still working so fine.
The pedal runs on 9V battery. As customary at this time, there is no input for a power supply.
If you ever get the chance to get such a rare pedal, go for it. The sound is really vintage and far away from the standard Cry Baby with fuzz face.
For 150 to 300 Euros the Colorsound Supa Wah Fuzz Swell is a bargain for all vintage fans.
