Its the same as above, just with the battery clips reversed.

Well I switched out the pots, the 10nf, 0.01uf and 47nf caps......still exactly the same problem and probe results as before

Note that it was designed with .15" pitch vero in mind.

Hey guys, I built this pedal from this vero layout, but its not working. no sound what so ever. I measured the transistors at 9.2v (all 3 of them at all 9 connections). Should they measure closer to 4.5v???

there's something seriously wrong with your build. Q1's and Q2's emitters go to ground. They have to measure 0V... The other readings are off as well.

Got my one working, doggy bradboard

Volume11 - have you got all 5 of the tracks cut?

Electric Warrior · Post by **Electric Warrior** » 29 Oct 2010, 23:33

even if he missed the track cuts the the emitter voltages should measure 0V, no?

Thanks for the quick replys... I'll check my traces and cuts when I get home from work, and I'll get back to you guys. I'll try to post some pics aswell

So... I didn't have the ground trace grounded to the rest of the circuit. It works now but, it's really noisy. Is that normal for this build?

Electric Warrior · Post by **Electric Warrior** » 01 Nov 2010, 20:34

It totally depends on your transistor selection. You might want to socket them first to try out what combination of gains/leakages works best for you.

dose anyone know what year the silicon transistors were introduced by Arbiter?

I made a Supafuzz enclosure from sheet stainless steel. Dimensions and shape are approximate, I couldn't find any info on that. In fact, i didn't even know what to type into google...

Looks like this:

Very Nice!

That is pretty bad ass, i'd happily have a Tone Bender MkII in an enclosure like that.

It isn't really hard to make provided you draw everything correctly on paper first, have access to a grinder and someone with a welder. I recently started getting ambitious about making a Univox Superfuzz orange/blue enclosure with the "Superfuzz" plate

Hey there,
Nothing that isn't known about this SupaFuzz, but it uses AC126 so I thought I'd share the guts with you. One Electroytic cap does not seem original and the pots have been changed. It has been well used and abused. Apart from that, it seems stock. The sound is pretty mushy due to failing electrolytic caps but the owner wanted to keep them in.

Electric Warrior · Post by **Electric Warrior** » 29 Nov 2011, 15:53

Wow, that looks bad. Whoever swapped the transitors and electrolytics (I think all of them are probaby replacements) must have done it with a blowtorch

Nyquist5 · Post by **Nyquist5** » 30 Nov 2011, 09:23

Yes, this pedal has been through rough times. The board is damaged and pretty much every single screw has been lost and replaced with an inappropriate one. And a Boss PSU was hardwired to the board, through a hole drilled in the front of the casing...

Talk about throwing money out of the window.

Even though the board shows some botched resoldering, I don't believe that the transistors have been replaced. Likewise, only one electrolytic has been replaced: from my experience, the other two definetly are contemporary of the pedal.

Electric Warrior · Post by **Electric Warrior** » 30 Nov 2011, 10:50

You mean the Erie electrolytic on the right? That one's contemporary to the pedal. I think Marshall even used that type in some amps.
In fact all the components appear to be from the right period, but I haven't seen any other Supa Fuzz with that exact types of electrolytics and transistors yet. Doesn't need to mean much, my collection of Supa Fuzz gut shots is somewhat limited, but on the other hand every single solder joint that belongs to a transistor or electrolytic looks like it's been badly messed with.

This is the closest match I can find in my database. All resistor types are identical:
