I got all my parts for the Fuzz Face from Banzai today! Before I solder anything I want to make sure i got it all right, so i need to ask :
The capacitors have longer and shorter legs... which way should I put them in?
The transistors have 3 legs, do these just go in the 3 holes that it covers?

1. The longer leg of the Cap is the Anode and should go to the non shaded place on the schematic.
2. the shorter leg should be on the side where it has -VE or a white stripe or something, that is the shaded end.
The transistors should be orientated as they are in the layout and the bottom leg (the emitter) is marked with a tab. You are best to use a socket so you can turn these around easily if you place them wrong as transistors are sensitive and can be destroyed by too much heat in soldering.
If you must solder them direcly then take care. The pinout from top to bottom is C, B, E in this layout.
Your AC128 pinout is like this:
When viewed from below.
Tabbed leg = E
middle leg = B
opposite end to tab = C
Take your time.

Ok, thanks. I will take my time with this!

Well, what should be waiting for me in the post room as I sashayed into work this morning, but the Os Fuzz. So far, I've used it to nearly kill one of our resident mini-amps, and prompted one of our lecturers to ask "Is it meant to do that?".
Thanks a million, Mike.

I told you it's fucking batty. Glad it got to you OK, when I was walking to the Post Office I realised I should have put some foam in to imprison the battery more tightly, as I think it moves like 1mm or something if you shake the box, n00b that I am. I'm sure it will be fine, it's trapped pretty good by the two switches and the circuit board which I angled to do just that.

ha! Found a cut trace that wasn't 100% cut. CrazyFuzz.
it's always something simple.

Sweet, the Mig 60 just became a whole new beast.

that sounds really cool. Its great to see you making custom things that you can't get out of a manufacturer

It's amazing really... he sorted out my convoluted request and managed to offer me exactly what I was after for an amazingly fair price. Mike is awesome... all there is to it.
Mike, I may also be looking at getting a TSA from you but I'm having a hard time finding demo's for it. When you finish the build, any chance you can demo it through a Harmonic Percolator and a fuzz of some sort, big muff type preferred? Demanding, ain't I?

I've afraid I have neither of those things on hand, but if you search youtube for "feedback loop" you should find some info, I have made it a better design by grounding the loop in bypass so you don't end up with phantom oscillations through the ground plane.

Don't suppose there can be any further improvement to cut the high pitched squeal if it's engaged before you start playing that I've read about... I'm sort of assuming it's really just the nature of the beast. Sort of "You want noise.... you got it." equation.
I'll seek out some demos, but I'm almost certain I'll be adding a TSA to my order as well.

Yeah there's no real way to stop it oscillating until you play I don't think, once you engage the loop it's going to oscillate if you have it set up to do so.

Something very similar to a Analogman Sun Face.
Controls for Volume, Bias, and Fuzz
MXR Sized case if possibly
Black n sparkle paint [ala lamp's crunch box]
purple led
mojo
can this happen?

Noirie
- Total Sonic Annihilation feedback looper
- £50 + shipping
- Metallic Light Blue
- Yellow LED.

The Sunface is just a modified FuzzFace, so yeah it could happen, I'll dig out the schematics for it.
This is my design for ends' A/B boost box.
I'm off home now, my eyes hurt.

If you could that would be great. I've been listening to samples of fuzz faces for a good hour now and i'm loving them. Around what price would this be leaning towards?

Transistors will be tricky.
Purple LEDs are also very expensive and hard to find. I'll get you a price tomorrow when I have done more research.
Here is Noirie's Fuzz War case before clearcoat:
