Thanks Ethan,
As a task like this is a bit above my DIY level, I am willing to give it a try I just want to double check. If I purchase the circuit board from the DIY recording equipment the parts list that would be left will be the following..?
Input and output connectors that match your audio equipment
One each: R4: 10K dual linear potentiometer SW1: 4PDT toggle switch, center off SW2: DPST toggle switch Plastic or metal case large enough to hold the parts and connectors
I am obviously averting purchasing there colour boards as they are a little to expensive. Have I understood this correctly.

I know they added a feature or two, so they can best tell you exactly what parts you need. Don't they sell a kit with everything included?

From my understanding they do sell the kit, you need the circuit board and a colour pallet which is their fancy name for a casing and connectors which costs $150 plus the circuit board which is $25. Now, if I am not mistaken that should in total be the whole kit. Hence, why I am curious if I can grab the circuit board from them, and source the other parts from somewhere else. I just need to understand what parts are left once I have purchased the circuit board?
Unless on the off chance $150 is a reasonable price and there is no point in trying to beat it. I mean for a few bob or two, I am happy to go with there casing but I get this feeling I can DIY it for much cheaper is that correct?

Yes, DIY seems a lot cheaper. But surely they show all the parts you need with the schematic.

I have the parts list from your audio express article, just trying to decipher it thats all.
I am sure they provide the schematic for the circuit board but not sure if that includes the whole schematic or just for the circuit board.

any one have any pointers for powering the transformers? is it 9v DC? what other wiring or components are needed to do this?

Audio transformers don't need to be powered, and the original Mojo Maestro in my article is passive and so needs no power.

Hi Ethan, I found your schematic for the passive version but I was wondering the "colour" circuit schematic looked like? I imagine the IC they have in there is just a buffer but I'm just curious what they're doing.
I could not find their schematic online. If anyone has a link, could you please put it up for me/us? Thanks!
One use I have found for subtle distortion is on my vocals, it adds a little bite or sizzle. I have used a plugin but an analog box would be cool. Now that I think about it, I wonder if the passive would work at mic level? Maybe it needs to be balanced?
Cheers, Rock

Dough! I'm answering my own question. The passive looks like it will never work with a mic signal, it's way too low, even with the germanium diodes.
never mind...as you were...

I would expect the schematic for the active version to be online, but I can't find it either.
