dang, that is a lot worse than a pedal not working !

Sorry to hear that, but I think you have the wrong forum altogether. May I suggest:

instead of retyping you could copy past your text.

AAARGGHH!! MUST...FIND...PICTURES...OF...CUTE...LITTLE...KITTENS!!!!


Almost better! Dang, John. Ya gotta warn people!

MUST...FIND...PICTURES...OF...CUTE...LITTLE...KITTENS!!!!

is that how you handle erectile dysfunction?! lol

I refuse to answer on the grounds...
After seeing the pic in that link, I needed to find some MindBleach. 

[MrStab]

now you made me look!! *gouges eyes out with spoon*

jokes aside, Jonny, you need to be a member to view posts on the forum you linked to, so maybe it'd be better copy/pasting your post here. this is a much better forum anyway.

OK sorry, here goes!

Hi guys, thought I would finally take the leap and build a SHO clone as it is apparently easy. I've wired everything up using this schematic



which was included with a kit I bought off ebay.

It passes sound but sounds like an extremely gated fuzz and the volume pot doesn't seem to do anything

I did a continuity test to make sure I hadn't bridged any tracks on the veroboard and it seemed fine, any ideas where I should start troubleshooting?




here's the veroboard wired up

and here's the pot



I think I have got all the components in the right places, I was a bit confused about the pot though as the pedal came with two wiring diagrams, one of which showed a ground wire going from lug 2 to the jack which I added.

Going to take the switch out of the equation tonight and see if that narrows it down

And here's the wiring diagram which I followed and seems to contradict the pot wiring guide in the schematic  :?



and finally here's the switch. I'm aware there's a lot of excess wire, my plan was to make sure it all worked and then tidy it up although I'm not sure that was the best idea  :|



OK so I've taken the switch out of the equation and it is still doing it, currently got it laid out like this



Here's a shot of the rear of the veroboard



The pedal only makes an audible sound when I play really hard and that is the earlier described farty fuzzy sound like a broken speaker!

[Kipper4]

Farty, sounds like it could be the transistor is not biased properly.
Double check your values.
Could be a blobby solder bridge.
101 possibilitys.

[jonnygreentrees]

also the volume pot doesn't seem to do anything to the sound...

is it worth buying another transistor to try in the socket?

[jonnygreentrees]

also I've got a multimetre are there any values I can measure to see if something isn't working properly (and how do I measure those values!?)

[LightSoundGeometry]

here is an example of  SHO I just did of you want to see one

mine has the power/smoothing cap problem going on ...I asked about it earlier and the forum said it was okay ..so I am selling it

but here is what it should look like





I can already see you are missing the first jumper right after C1

[jonnygreentrees]

thanks that's really helpful!

did you use the same layout as me?

I have two jumpers on the board, not sure if that's clear from the photo?

[LightSoundGeometry]

no you got it then, its hard to see but there is only two

I think its a solder problem, your layout is sloppy and not tight. could be a case of not enough practice.

and dont buy any more kits , just buy all the pieces yourself

[jonnygreentrees]

yeah it's only my third time soldering ever and my first ever pedal build!

which bit is sloppy? tips for improvement welcome

[LightSoundGeometry]

well I would just practice taking components on and off ..solder/desolder

your joints are sloppy, pull everything tight and neat ..takes time. I am still new myself
