Electro Harmonix Knockout Attack Equalizer

"The Knockout is a powerful two-filter combination that can make your Les Paul sound like a Strat and your Strat sound like a Tele. Its secret...the Knockout has a 7 pole filter for sculpting the low end of your mids and a 6 pole filter to shape the top end of the mids. This provides incredible tone shaping. Use after distortion to bring out the heavy weight punch of the metal masters. The Knockout is also truly amazing on Bass."

Jen Double Sound Fuzz Wah

Couldn't really find a good description of this pedal other then it's a Fuzz-Wah produced in the 70's by Jen. Here's my take based on the schematic. Just like many of the other fuzz wahs I've seen and working on layouts for this is essentially a classic inductor wah with a fuzzface type fuzz. There's a few differences I've noticed compared to a lot of the others. First, there is no control over the amount of output of the fuzz, ie it's set. Second, unlike a lot of the others this one has the fuzz in front of the wah, instead of behind the wah. From the video I found of it, I'm defiantly digging the fuzz and think the component changes gives it a little something different that would be nice as a stand alone fuzz, and the wah has a nice sweep to it as well.

Quick Note: The fuzz should be wired in front of the wah.

Colorsound Fuzz Wah/Fuzz Wah Straight/Wow Fuzz

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.
