So, I decided to make an instructable! this is my 1st one, please feel free to comment on anything and everything.   .... pleeaase comment!

Here's the video of how to do it!


Note: Please Read all steps and read them carefully (if youre just starting at this stuff that is!) if you want to make this right! It should be easy if you follow the steps well.  This is more of a beginners project, you could still make it otherwise!

If you have tried and tried to make guitar effects pedals and have not succeeded, this instructable is for you! Or if this is your very first one then this is definitely the place for you to be. I have not found one instructable or website that gives clear step by step instructions on how to make guitar effects pedals. I found one quite clear with the instructions, and all the comments helped out too. It just lacked the Step by Step part. This is it: www.instructables.com/id/Very_simple_and_cheap_GuitarBass_distortion_pedal/
I am using the design (schematic) from this one as it is a very simple distortion pedal.

lets get started!


Okay so Amerinidiot1231 was kind enough to create the perf board layout schematic, so that is attached on this page if you would like to refer to it.

Step 1: Important Step: Resistors

Resistors do basically what it sounds like they do! Resistors Resist the amount of current flowing through a circuit. (a circuit is a path of electricity. Basically if you connected a battery to a light you would have one of the simplest circuits possible)
So for example if you made the above circuit by connecting a battery to a light and then added a resistor anywhere in the circuit the light would be less bright than it was before. The amount of resistance in a circuit depends on how much resistance the resistor(s) have. Think of it as a river! the water flowing through the river is the current flowing through the circuit, the larger rocks in the river slow down the water (as the resistors lessen the current).  Resistors will look like the resistor in the picture below, they usually will not be any other shape, they slightly vary in size and they will sometimes vary in color other than the creamy color like the one below, I have also posted a picture of a blue one so that you can see what I mean when I say they might vary in color other than the creamy color one below. So now that you know what they look like, you will hopefully not mistake them for anything else!

Reading Resistors
For windows (not sure if it will work for macintosh or other operating systems)

it is So much easier just use this program to read your resistors: www.mitmaro.ca/oldsite/files/rr.zip
note: this program will not give you any viruses. All you need to do to use it is click on the link above and then click SAVE and save it to your desktop or somewhere else that you will remember it. Once it is saved, click open. Once you have opened it Double-click on resistor reader and then click extract all, then click next, next again, make sure you have selected the checkbox that says "Show extracted files" Click Finish and then a window will pop up with some files double-click on resistor reader! now I will tell you how to use it: (do this when you need to have your resistors read)place the resistor down on your computer desk facing your computer. Place it so the gold band is facing the right side of your screen. Count the number of bands on the resistor. If it is four bands then under resistor type, select four band, if it is five bands select five band. now, start from left to right select the color on the left matching the color on the left of the resistor and so on the band on the right will usually be silver of gold. It is pretty straight foreward I guess.

Now for macs and other systems!
There is this website www.pealefamily.net/tech/resistor/ It only does four bands though I think that is probably all you will be dealing with though. But you need to read the above step for windows users because the one you will be using will be much the same. *READ ABOVE STEP!

So thats step 1!

Oh and one last note: you can combine resistors to make one resistor like lets say you need 22 ohm resistor, you can combine two 11 ohm resistors. and resistors are not directional, so you can put them either way around in the circuit!
<p>Hey Guys! So I decided to make this my first project and it came out sounding amazing! Here's my layout if you want to use it! Thanks for this awesome Tutorial!</p>
What diode you use
<p>Would be really helpful if someone could show me how to connect the Indication LED please :) Thanks</p>
<p>To add a power indication LED just put an LED in series with a resistor across the battery. You can determine the resistor value you need by using:<br>(Vsupply-Vled)/0.020<br>If you find the LED is too bright, just use 0.010 instead of 0.020; LEDs are bright these days! Oh yes, just some very approximate common forward voltages of LEDs (Vled):<br>Red - 1.5V<br>Blue - 3V<br>Green - 1.5V<br>Yellow - 1.5V<br><br>Please not these values are just vanilla values that will work and might be out by hundreds of millivolts, but they will get you on the way without needing you to know much (LEDs don't actually have a &quot;forward voltage&quot;, this is just a value we use to characterize the LED in it's linear-ish region where it's usually used).</p>
<p>Mods:<br>- Yellow 3 mm LED's for the diodes<br>- Added a pot between emitter and ground for gain control<br>- High-pass filter on the output stage for tone control. Can be modified to a low-pass by switching the positions of the resistor and pot with the capacitor. I don't know why you'd want an LPF on a fuzz though - you'd just undo all the fuzziness!</p><p>I will probably crack it open and switch R1 out for a higher value (500K to 1M) to get more gain. It's crisp as it is, but I want this beast to bite!</p>
<p>Hey Theophallus I'm trying to build the fuzz you're showing here and I would be glad if you could post some pictures of the inside so I can have a better understanding on how everything comes together (it's the first time I build a pedal)</p><p>Thanks !</p>
<p>I think I accidentaly built a radio.. Someone knows what happened there. </p><p>Also I am only able to hear sound if I play really hard..</p>
<p>it is because the input dont have a low an high pass filter, this circuit is too simply </p>
<p>Me to! When i set volume on guitar down I hear some radio station (probably AM because its not in my country language).</p>
Try to put the potentiometer for volume
I currently have a 1.5 Mohm Resistor as r1 I guess I'm gonna try to put my 100kohm potetiometer there thx for the reply^^
<p>If you use 1.5Mohm as r1 it is restricting the current to flow. 1.5Mohm is 1,500,000 ohm vs 100kohm is 100,000 ohm. the best is to stick to something around the 100kohm.</p>
<p>Hey, I am building it this way, as you can see i settled two sets of diodes and a switch between them in order to select which path to follow, the volume and the distor knobs are in place but i have not soldered anything... do you consider this will work?, on the other hand. what would be the recomended voltage for it to run? 9v dc tops?</p><p>thank you so much :D your work on this one is amazing, we'd love hearing a bit of it working</p>
<p>Hi, I built this as per the schematic but I'm having the same problem as JoshT15. Without the battery, there is just a plain signal but with the battery there is a lowered signal with no fuzz?</p>
<p>I've breadboarded this circuit 3 separate times, same thing each time: it lowers the strength of the signal, no distortion. When I disconnect the power source, it allows the louder, clean original signal through? </p><p>This is driving me crazy! I've also tried lowering R1 impedance, and different diodes...any idea what's going on?</p>
<p>This is happening to me too! Did you find an answer to this?</p>
Hey, I successfully made the pedal. (Thank you so much for the tutorial.) Does anyone know how to eliminate the buzz/static from the pedal? There's quite a lot, but the guitar is still going through. If someone could help, that would be awesome.
I have the same problem! Any advice would be great. Is it a grounding problem?
<p>I did it, and sounds great BUT:<br>-first cap, used a 102 (0.001uF), distortion will be clear and bright<br>-gain pot didn't work there, instead I putted between emitter and ground, works great<br>-volume was low so I changed R1 for a 1.5 Mohm that had around<br>-NPN was a 8050 or S8050, diodes a pair of 1n4148</p><p>this was my first pedal and it's great for experimenting, I'll keep doing it until I have no more ideas!<br> volume pot worked until I did my gain version, if I put C2 before the output will work?</p><p>sounds nice alone in clean amp, for boosting the amps distortion is great!</p><p>P.D: if it doesn't work, try other NPN, I did it three times because the first 2 shorted or something. <br>also check if yours is ECB or EBC</p>
<p>i recommend using the gain pot where R3 is. R1 and R2 must be set so colector voltage stays around half baterry supply at 4.5v to avoid to avoid saturation. </p>
<p>Actually I did it like this </p>
<p>how would i wire a power supply to that?</p>
<p>you can use a battery clip connected where it says +9 and -9</p>
<p>Hi, great tutorial:)</p><p>But I had an issue. I tried a lot of combination of components but it really didnt work. Eventually I found out that the signal from guitar is too small and only if I played really strong, the sound came out. Soo I made simple pre-amp. </p><p>I hope that it will helpl somebody like me.</p>
<p>Eu fiz esse pedal e ficou muito bom. S&oacute; faltou incluir o potenciometro de ajuste de distor&ccedil;&atilde;o e o bot&atilde;o de ligar e desligar o circuito. Estou adaptando.</p>
Well i can say this guide was very helpful. Except the dpdt switch toggle part maybe? I tried it but the switch only works with the clean sound part. Buuut maybe i've just done it wrong so i'm gonna try again. Thanka for this, you rock!
<p>Thanks ! <br><br>Someone knows how to put a True ByPass on it ?</p><p>I'm thinking to put a NC switch between both Jacks (it jumps the whole circuit) and a NO switch between +9V and the circuit. What do you think about it ?</p>
About germanium transistors,could i use just any germanium transistors? Or is there some better than other? <br>-and is there a specific voltage for the capacitors?
Thanks for all the info. Will be making one of these as soon as I gather the parts. Also which diod would be good for a metal distortion? Thanks again..
<p>The link to the video is broken :(</p>
<p>where do put the tone pot? can anyone suggest me please!?</p>
<p>where do put the tone pot? can anyone suggest me please!?</p>
<p>Here's a pic if anyone wants to take a gander, C1 is 100uf, C2 is 10uf, I have checked and rechecked polarities, etc.</p><p>Power supply is 6V right now, but I've tried everything from 3V to 12V. And again, a good few different diodes.</p>
<p>oh and I did have the emitter grounded, just had it removed while messing around for the picture lol</p>
<p>The Youtube video is not working.</p><p>Is there a video or an audio clip somewhere where we can hear what this pedal sounds like...?</p><p>Does the type of resistor matter...? I went on eBay to order some resistors and all of a sudden I see there are a few different types of resistorrs (Carbon Film, Metal Film, Carbon Comp, Metal Oxide Film). I know from dealing with high end audio that some components (like capacitors) sound better, are more silent, and are more musical than others. Does it make any difference what kind of resistor you use in this circuit...?</p><p>How about capacitors. Are there certain capacitor types you recommend...?</p><p>I'm very interested to hear what this sounds like....</p>
<p>I have had alredy built one of these. I can tell you it will sound like a sharp low-gain distortion, down to mild overdrive. </p><p>Go for carbon/metal film resistors. Metal film are better, but they are more expensive, but as we are not working with high voltages you won't see the difference. For capacitors, im not sure, but for these circuits i think polyester are the best.</p><p>If this is your first pedal build, go for it. But if you some more specific tones, i can recomend you better ones.</p>
Thanks Miguel, <br>That's good info about the resistors and caps....<br>I'd certainly be interested in other distortion pedals...<br>I've been playing for over 40 years now, and am familiar with a lot of the brand name pro units, which is what I would be comparing the sound to, I just can't afford the price of the pedals these days, so I'd be willing to put the time and effort into building my own. So, yeah, if you know of some better sounding, more feature laden DIY boxes, I'd really appreciate if you could turn me on to them... ;-)
<p>So, i would recommend you to check these three websites:</p><p>runoffgroove.com</p><p>tonepad.com</p><p>sabrotone.com</p><p>Both have great schematics and layouts to build pro pedals. There is also the: bigmuffpage.com which is specialized only in the electro harmonix big muff Pi. It would be helpful to know your tastes so i could recommend you more specific pedals. As i am more into metal, i have more layouts of marshall, mesa boogie and other amps' preamp to use as a distortion pedal.</p>
<p>Thanks, Miguel, I'll certainly be checking those sites out. You know, I like a guitar tone that can &quot;sing&quot;, which basically means it has good sustain, so I do tend to like a compressed sound. As far as distortion goes, I like a number of types of distortion. The first being the kind of distortion that is touch sensitive, for playing blues, so when you strike the string hard, it breaks up, but when you pick softer its not hardly there. So, there's blues distortion. Then, there's the distortion that sounds like an overdriven Marshall, again, with sustain, but not harsh at all. I like a warm, tube kind of distortion. A distortion with a tone control to dial in the amount of mids and treble works best for me, as I don't like a muffled sound at all. Leslie West had a great distortion on Mississippi Queen. Randy Bachman had a great distortion, Mark Farner, Hendrix, and so on, for Classic Rock distortion. Though I tend to listen a lot more to virtuoso players now, like John Petrucci, Steve Morse, Joe Satriani, Steve Vai, Etc. and again, what all these players have in common with their tone is clarity, warmth, and sustain. So, I cover a range from Blues based, Classic Rock, into more modern progressive music. I don't do metal at all, although I'll listen to metal and especially check out the soloing. Metal technique is awesome, but it's just not what I play, ya know? I grew up in 60's, in the era of classic rock, and my ear has always been drawn to players with great technique, and while I do play blues occassionally, I'm not a 3 chord blues kind of guy, I'm more like a 12 Chord blues kind of player, as I like harmonic complexity and music that interesting, and not repetitive. </p>
<p>To my amazement, it worked despite the fact that I used no structure and only a few wires, soldering most components directly to each other.</p>
<p>What am I doing wrong?</p>
<p>Could someone show me this project on a breadboard?</p>
<p>I made it haha This project is really simple and perfect to learn offboard wiring (for beginners) ;) </p>
<p>just find out how rectifier diodes look like, i was so wrong xD.</p>
<p>Works for me - made on a business card because no perf board available - will add a gain pot , volume pot and tone pot (I must have some knocking about .</p><p>The capacitors should be nf values not uf in my opinion.</p>
<p>actually it looks good with business card :) </p>
<p>Cheers - was fun and it works well and its still on the card</p>
Could I use a 1000uf capacitor for some super bassy sound or would that just not work?
<p>hi! with another transistor and correct resistors it works so fine on my bassline synthesizer!!! sounds so nasty!!! will build other trying some variations based on other projects ;)</p>
<p>hi! i'm trying a random transistor and no distortion, just a little less volume and bass ... trying to build with parts found in some broken hardware i have around... this will be the mission of the month :P</p>
