The Colorsound Fuzz-Wah,
or to be exact the Colorsound Wow-Fuzz! A new version of a funk-tastic
old timer. The original 1970’s two transistor silicon distortion stage
delivers the fuzz and the classic inductor based Colorsound wah circuit
gives you the wow!
Ah, the inductor based circuit you say. Been awhile since Colorsound did
that, right? That’s right and who better to achieve time machine like
accuracy on such a wah circuit than monsieur Castledine of Castledine
Electronics fame. From the reproduction circuit board to the custom
wound vintage specification inductor, this is a genuine and bona fide
Colorsound wah in everyway. The huge soaring sweep, highs that level
mountain tops and low mids that sink ships. Fast reacting prono
soundtrack like cool, nothing chukka-wah’s like a Colorsound. Buddying
up along side this specially falvoured wah circuit we have the authentic
fuzz stage as featured in all the early Colorsound Fuzz-Wah’s. Voltage
feedback family ahoy. This transistorized silicon fuzz circuit is biased
for a smooth and mellow fuzz tone. Rich with heavy density that gels
perfectly into the wah stage once engaged.
Independently switchable
stages. In other words one switch to engage each circuit. It may seem a
little odd at first having both mounted at the front of pedal but it
does work surprisingly well indeed. After a little bonding session with
the pedal it becomes quite easy to select the circuit you desire or even
engage/disengage both simultaneously. It is most certainly not rocket
science but a little introductory time is never a bad thing.
You want to use DPDT switches to turn each effect on and off, unless
you’re going to put LEDs in to see what’s on and off, and the wah comes
first in the circuit.
A quick note: The original transistors have a pinout of BCE top to bottom on the flat side, but since they can be rather pricey these days I decided to make the layout using the more common CBE pinout. So if you decide to hunt down the original transistors be aware that you will need to twist 2 of the pins. Not a big deal, but can be kind of annoying for those of us that are a little on the meticulous side.
Also, the description I posted is for the Sola Sound reproduction made by the captain. He switched the 5k trimmer to a 47k, so you can put a 50k no problem.
