Was wondering if someone could help me tell the parts on this schematic?!?!?!?!

http://juansolo.demon.co.uk/stompage/schematics/IVIark/Maestro%20MFZ-1%20Fuzz.png

From what I can tell I need:

2 - 2.2m resistors
3 - 1m Resistor
1 - 10nf Capacitor
1- 100uf 50 Capacitor
1 - 100nf capacitor
2 - 2.2uf capacitors
1 - 100pf capacitor
2 - Diodes
1 - 22O NF capacitor
1 - 10k resistor
AND OF COURSE that IC chip.

Any help would be great.

looks fine but the 100u doesn't need to be 50V (it won't hurt if it is though). 16V or more is fine if you follow the max voltage x1.5 rule

a 16V one will be slightly smaller and cheaper

ashton8504

max voltage x1.5 rule

what is this?

I am such a noob its not even funny. However, are all my parts right? if sooo woo hoo been teaching myself

Caps have a voltage value you shouldn't go above. So a cap may be rated 16V, 25V, 50V etc, as well as rated for its capacitance (the 100u or 10n or what have you).

A safe, conservative rule is to have a cap's voltage rating AT LEAST one and a half times any voltage it will ever meet. This circuit is 9V, so to be safe for long lasting caps, use at least one and a half times 9. That is 13.5V, next standard rating above 13.5V is 16V.

And yes, parts are fine, unless you want to save a few pennies and get a lower rated 100u cap.

THANK YOU SO MUCH FOR YOUR HELP

ashton8504

for the jumper cables (if i am using the correct terms) can you use just standard wire? :icon_neutral: :icon_exclaim: :icon_confused: :-*

Pretty much. Solid core sometimes snaps. And you don't want it too thick to go through the holes.

 "standard" wire is fine , stranded is prolly best like some thing in the 20's gauge , not too thin or thick ... , solid core isnt the best .

looks like the 100 picofarad cap is an orangie , or ceramic type , then there are the films , but the 2.2's are electros .

dont forget the stomp switch , led if you want , resistor for the led , so if its an ultra bright led you may want like a ten k or around there , normal led around a 1 k .

dont forget the pots , 25k a 100k b , other assorted pita's : dc jack , battery snap  , socket for the chip ,  input jack should be stereo if using a battery , mono output jack is fine , knobs , chassis , and finishing materials and you will be all set ...

pssst ... tayda has a sale on pal ...

http://www.taydaelectronics.com/

and yes i think thats the right socket i mean , the chip has 8 pins right ?

dont get those from there though ! they are very cheap elsewhere , 2 for a buck at rat shack ,i think 16 cents at tayda .

You won't likely find the TL022 in any stores that cater to hobbyists, because it is long obsolete. An exact equivalent that Will work and is readily available is the TL072. I would not have recommended this Vero layout as a first build. Not that it's too complex...the level of difficulty is OK. The problem is that there is so much that the drawing does not tell you. You are absolutely right to be confused!

A first build should have a fully annotated parts list and detailed instructions for making Every connection. Also important are typical voltage readings and a cadre of people who have built the whatever-it-is and can help when your build does not work and you want to tear your fur out.

If you go ahead with this, other Forum residents will work with you as you learn. Or there's a Beginner Project here

http://www.diystompboxes.com/smfforum/index.php?board=6.0

that would be a good starting point.

This is a great place to learn i've been here less than two months and i've learnt loads thanks to the guys here. Welcome to pedal building and the forum buddy
Ma throats as dry as an overcooked kipper.


Smoke me a Kipper. I'll be back for breakfast.

I suggest you find a good online retailer.  I use mouser.com, but looks like you might he overseas?  Then, buy five times as many of those components as you need for that project.  Jacks, pots, and especially switches can start to add up, but caps and resistors are practically free once you've paid for shipping!  You will have spares for when you break off a lead or burn something out.  Maybe you'll build another for a friend.  If nothing else, these are pretty common values which could be used in many other future builds.

By the time you make this pedal work, and especially if you hang out around here, you WILL want to build more.

I'd throw a breadboard in the order, too.

And if you don't already have a decent digital multimeter, get one.

To everyone thanks for the support and the info.

\m/ keep the soldering iron hot and i will try keep my frustrations down on my first build \m/

Also assuming for the input use a stereo (so i can use a battery and/or a power adapter) and then a mono output would be fine? :icon_rolleyes:

Thanks for the input. Looked at that link but for some reason it makes this all even more confusing. The original picture i posted for a maestro fuzz clone makes more sense and helps me see the big picture. Short hand schematics really throws me off  ??? Also in this link it seems they are soldering parts together, is this to bypass jumper cables (sorry if jargon is off).

It's your call, and you have to ride the horse on which you feel comfortable. I did say that the Vero layout leaves out a lot of information, like a schematic. You Will have to learn to read a schem and relate it to physical wiring at some point if you are serious. The Beginner Project is done on pad-per-hole perf rather than Vero, so the connection method is different. But either method will get you to the same place if used correctly. The pics in the Beginner project spell out the off-board connections explicitly, which is very helpful to many people.

yes , but small bear is offering some great advice ...

please be patient and attempt to digest my inane ramblings , personally , i have found with most of MY diy experience , patience is THE main ingredient .

as you may be well aware , there is a section here called "the beginner project" this project/section was actually designed to answer most of the questions you have atm . the only project in this section is the NPB boost by Gus Smalley , it is a pedal much like the popular pedal ehx lpb-1 , mxr micro amp , even similar in concept to the vexz $uper hard on (yer piggy bank) aka crack is ok  (but i much prefer sherm) . Mr. Smalley's renowned  booster circuit can also be used as a building block for other , more complicated pedal designs . i actually built this as a first project , on breadboard , then perf , even dualie  vero's for stereo . despite the fact that in years past i had what i would consider a good amount of experience ruining things with a soldering iron , mainly hardware hacking  (once i "fixed" a flash light ) , but not so much building from scratch (unless you count the paiaa gemini amp , ring mod , some 555 opto theramins , and dual apc's ) toot toot .  anyway , i have used this circuit in "my own pedal design" ( a complete theft / text book example to leave well enough alone and timeless source for endless hours of belly laughs to all whom have laid eyes on it ) ,  i have also used the circuit found in the beginner project section in a few my "amps" ( shame boxes ) as well .

i do admit , when i first came here i did notice a few very similar threads with similar responses , then when i looked at the section , at first , i was all " man i don't need this " . looking back at that moment , i couldn't have been wronger , and quite honestly i am glad choose to spend time building it because that circuit , well it has saved my butt three times now . i would say it would be a huge mis-step to ignore the beginner project , its an excellent process , excellent circuit (you will use it) , it is very inexpensive and after all this project /section was actually designed to answer all the questions you have atm . it is all there  :)

i would suggest that you begin to put together a master list of parts , first the parts for the npn boost AND the maestro  , maybe someone would look this over with you via pm ... in the meantime , do some more research , read a bit and watch some starter videos ( i will pm you some good ones : digit2 phase2 , not mine they are terrible ) . this process CAN be very fun and rewarding , when you are properly prepared , attempting to approach a project in the dark r, well , it really takes the fun out of it . a great man once said the finished project is just the junk left over from doing the work , doing the work is really what its all about .

looking at your situation i completely understand why you may feel overwhelmed from time to time , but , when you spend time going thru the excellently documented beginner section , proceed thru that build you will have learned to read a schematic , have a grasp on the function of the components in the circuit , you will have the proper foundation to move on comfortably .
