Tayda is a very cheap place to buy components, and I've been very happy with the parts. Much cheaper than European or US parts. Great for LEDs, LED mounts, capacitors, resistors, enclosures, pots, etc.
Fuzz pedals are pretty simple, really. You're really just overloading a circuit. Unless you're buying some really expensive parts, and I don't think that's necessary, you should not have to spend more than $50 (US$) on the high side to wire up one of your own. I haven't boxed this one yet but I do have a simple fuzz circuit on a bread board -- and it sounds pretty nice! I put it together in about 20-30 minutes with about $4 or $5 in parts. You should give it a try.
You can use PNP transistors with a power supply but you must reverse the polarity and make sure you do not power NPN Negative ground pedals from the same power supply. G
This is a positive ground pedal. You can use it with other neg ground pedals but they can not share the same power supply. Running a them on batteries is fine. G
Hello Graeme, First off, thank you for this outstanding video! You've done a great job building and explaining the construction process of this tone bender and I appreciate that you've left the videos up on RUclips. I especially appreciate you showing us how to properly bias the transistor by doing it audibly. I noticed you only used one trim pot - would you mind commenting on which transistor utilized the trim pot please? One more question if I may, how did you mount the circuit board in the chassis? I'm definitely building one of these pedals. Among tone benders, the Mk I is my favorite and your pedal sounds fantastic! Atb - Luther
Hi! Thanks for the comment, I really appreciate that. From memory, I think the trimmer was to the collector of Q3. I built another MK1 last year and I breadboarded the circuit and selected the transistors by hand, auditioning them until I found what I wanted. I uploaded a short demo video if you'd like to hear it. Regards, Graeme.
Excuse me... this is a really great video :-) but how do you do the ground on a point to point wired circuit? You just solder the side of the component that needs to be grounded on the board?
@blondegraemey Do you buy tested transistors or bulks and test them yourself?.How much leakage would be good for this circuit and how is it measured??. P.s.:Great video.I would love to build a pedal like that if i had knowledge and skills
I couldn't say? If your drill is powerful and fast enough you should drill aluminum with ease. It is a soft metal. I find re-chargable cordless drills are to slow. G
Hi! Great channel! I have a question I was hoping you could answer if you have the time. What kind of decal did you use for your MKI clone? I've done my own inkjet water decals for pedals but never white on a darker surface. Hope you can shine a light on this :)
I didn't use vero board with this pedal, It is point to point wired just like the originals. I can't remember where I got all the info from now, it was a while ago. G
Graemey, WTFook soldering station is that anyway? It looks like a travel model in a sanitary White a medical tech might have had. Did those xistors come from the local Radio Spares?
@TR1VO5 Hell no :D For example the Zvex fuzz factory costs about 300 bucks, i cloned it for just 23bucks ;) He used very expensive components, you can use less expensive ones.
Thanks for the video. I used this to help me build mine. However the pedal sounds very bad and extremely over driven. Do you think my transistors have too much gain? If so how much gain should they have? Thanks, Tim
How have you been? Have you built any new pedals? Your Rangemaster Treble Booster kit by Vintage Pedal Workshop, is the best build I have ever heard. I wish you could go back and talk about both these builds and teach us "the next generation" how to do it and what you have learned over the years. Thank you for sharing your wisdom with us!!!
That semiconductor Analyzer blew my freaking mind.
I gotta buy that soon.

Hey Graeme,
I really enjoy watching both parts. Very informative. Well done mate!!
Rob
Thanks Rob! Great job with your Mk3 demo mate, brilliant playing as always. G

that semiconductor tester is dope!
Great sounding MKI by the way !
This is a positive ground pedal. You can use it with other neg ground pedals but they can not share the same power supply. Running a them on batteries is fine. G
The drill is an old mains Black and Decker. You need drill bits suitable for drilling metal. If yours are blunt, they will need to be replaced. G
Well done. Interesting.
Brilliant !! .... Thanks for posting !!
congratulations! it was very good!
you could tell me the relationship of components (and values) used this pedal?
Q1 69, Q2 and Q3 about 90/100 all had very low leakage but I've heard that leakage isn't such a problem in this circuit. G
This pedal really has the MOJO!
Cheers! I play in a few bands here and there but just covers and stuff for fun. Im too old for originals now! G

Thanks for the comment Blake, good luck with the building! G
Thanks.
Yep, you are right both times. G
Btw:That semiconductor analyser must be a swell tool too have!!
Nice Vid! Also, nice construction Technique. Is is much trouble in England getting parts & what not? Anyway your box came out well indeed!
Excuse me... this is a really great video :-) but how do you do the ground on a point to point wired circuit? You just solder the side of the component that needs to be grounded on the board?
The one that's connected with Q3 base and the first 100nF cap I think.

i think it's more expensive to built a fuzz than buy an fuzz. but it seems to be fun.
Did i get this right:You used an OC75 for Q1 and ac125´s for Q2-3??
Are´nt those OC75´s hard to track down?...(And expensive)
Hi! Great channel! I have a question I was hoping you could answer if you have the time.
What kind of decal did you use for your MKI clone? I've done my own inkjet water decals for pedals but never white on a darker surface.

Hello, sounds good! What hfe and leakage did you end up using? I've built one myself and try to tune it up. Got Q1 60 270ua Q2 93 150ua Q3 65 160ua.
I didn't use vero board with this pedal, It is point to point wired just like the originals. I can't remember where I got all the info from now, it was a while ago. G
Maplins and RS. Both are online stores. G
Q1 around 80/90. Q2 and Q3 in low hundreds 120/130. That's what I used from what I remember. G
Graemey, WTFook soldering station is that anyway? It looks like a travel model in a sanitary White a medical tech might have had. Did those xistors come
from the local Radio Spares?
which 8.2k resistor did you replace with the 10k trim?
@TR1VO5 Hell no :D
For example the Zvex fuzz factory costs about 300 bucks, i cloned it for just 23bucks ;)
He used very expensive components, you can use less expensive ones.
so where do you buy your supplies from case electronics? any recomendations
thanks!
J
Would it be possible for you to upload a parts list and where to buy them? thanks!
how did you learn to read schematics? I'm trying to build a fuzz face and I don't understand the schematics :(
What would be an ideal hfe for the OC75 ? Thanks !
I cant find that point to point board layout , on google images .
Could you tell me the recomended values for Ge´s and/or leakage? thank you
I bought it from Maplins in the UK. G
They are Metallised Polypropylene. G
Hi, do you have a pdf available of that folder you were flipping through?
Yes just use your search engine, loads of mk1 info out there. G
All over the net. Try Free Stompboxes and Fuzz Central. Just google them. G
Is the trimpot connected to Q3 collector ?
what kind of capacitors are those
Thanks for the video. I used this to help me build mine. However the pedal sounds very bad and extremely over driven. Do you think my transistors have too much gain? If so how much gain should they have? Thanks, Tim
what capacitors and electrolytics did you use?
where did you get your components from? sorry sure you've been asked before
where did you buy the components? thx
Hi , I been having trouble trying to find the build schematic you used Please can you help . Thanks Stu.
Going from memory, I think I got most of the info from stompboxes.co.uk

That's not the proper way to solder mate. Soldering that way is prone to cold solder joints. You must heat the contact area then apply the solder.
No sorry man. G
