Twinface (with VIDEO)

[jfk1063]

Hi!
I'm really pleased with how this pedal turned out so I decided to make a demo-video for it.
For the germanium side I used NOS AC128 transistors and NOS resistors and capacitors. For the silicon side I used NOS BC183A transistors and regular new resistors and capacitors. The only thing I added was a bodycontrol which is a basscut. I think this a really nice addition making the fuzz more versatile.

Enjoy the video and please like&subscribe .

Super excited to do this build now. Thank you for sharing sounds amazing.

That is awesome. Where did you get the LED bezel from? +1 for the bass cut in a FF!

Thanks Jamie!
I think from Musikding or Banzai.

If there were only a more concise way to say 10000pf, they could've made that capacitor smaller.

Great video! Great build!

Nice sound! Nice build! Nice guitar! Nice shirt!

They also needed room for all the mojo?

Nice sound! Nice build! Nice guitar! Nice shirt!

Thanks! I got the shirt as a Christmas present.

Cheers

Sounds awesome! How did you install the bass cut?

very carefully!

Haha sorry, it's a 500k pot with a 2nf cap before the input.

Where did you get the knobs from? I got somr from LMS but I my pots are about 2mm too short! LMS does say you need longer than normal pots for them.
I might have to counter sink the enclosure on the inside to get them to fit.
Did you use different pots or anything?

I got them here:

British :: Pointer :: Plastic :: Knobs :: Electromechanical :: Electronic Parts :: Banzai Music GmbH

And I used regular pots and they fit fine.
Best of luck!

Perfect. Thanks for that I iwll get a couple and see how I go!

I’m currently building one of these for a friend and Im new to this stuff, I’m interested in using that bass cut pot mod I was wondering how you wired that with the input and if you use the three pins on the pit

It's a blend between two input caps so input goes to the wiper aka lug 2, the caps connect to lugs 1 and 3 with one lead, respectively, and the other leads of the caps both connect to the base of Q1.
For less bass use a smaller cap than the stock 2u2.

I think I actually just did this, but there might be better ways like mentioned above.

You can see it here:

So in the end its a Treble booster with a Fuzz.

I built a Twin Face earlier this year and put a bass cut control before the input as well. I got the idea from the OP, but found a decent article on it that helped me out.

The article assumes the control is going on a guitar, but it's the same principle. The pot and cap are inserted between the input jack and the PCB input.
