Pro tip from someone who regularly built small boxes like these in his old workplace, but mainly as custom meters for specialty applications: When drilling holes into any kind of enclosure, put some masking/painters tape on top of it, mark on top of the tape and drill through the tape. That way you don't scratch up the finish with the metal shavings on your drill bit and/or leave permanent marks on the surface with your pen. And when you try to solder a bit of wire to a terminal or pin, put some solder both on the end of the wire and the target pin beforehand. That makes the job a lot easier! :)
Hey there, nice video! One thing though : you don't have to remember where the dot is under the DIP8 socket, it has a curve that needs to match at one side, that you clearly missed, cause you soldered the socket upside down :) Yet again, thanx for great content!
I've been doing some minor soldering and building, but nothing like this- thanks for filming the whole thing and being honest with the issues. I think I might be able to handle it.
Definitely! These ready made PCBs make everything easier when starting out - You can always move on to vero builds later on. The Tayda RAT is a great place to start, but if you want something easier to begin the Tayda Guitar Power Boost is also great (gives you the option of building several different boost pedals by varying your components) and only runs about $6 USD.
Baldur's Workbench - Home DIY Engineering Very cool! Thanks for the tip! I have bought a few things from Tayda already but had not poked around the PCBs at all!
The 9v dc jack in the parts list is a 2 prong, and one of the caps on the list thats supposed to be a film box is linked to an electrolytic cap. Just couple things to note if anyone is tackling this project. Using the 2 prong dc jack is fine if you arent doing a battery, but if going that route, just use mono jacks for the input and out jacks. Hope this is helpful for someone
I like the price of your kit and how you assemble it I've also looked online at a lot of kits and a lot of them will cost as much as a pedal cost so there's got to be a more cost-effective way to build them.
you are forgetting the value of learning. the price in dollars may be the same, but the VALUE is way higher. learning new skills is always a good idea.
I know this is ancient history in computing terms, but I looked at the schematic shown on the linked website for the kit. It shows pin 1 and pin 8 being connected on the opamp. The opamp is a TL071CP, and on that opamp, pin 8 is not used. However, on the original RAT schematic (using the LM308) pin 1 and 8 ARE connected. On the LM308 pin 8 is the "COMP2" connection and pin5 is not connected. On the TL071CP pin 5 is the "offset null 2" and pin 8 is the n/c. So I think the schematic is using the wrong pin number, but hopefully the PCB is actually connecting pins 1 and 5 via C3 because I can't see the PCB that well. (I only worked this out so I could breadboard the circuit and it was bugging me that an unused pin was being used)
Thanks for the video! One small comment, the reason for the sockets is not only for changing the IC, some ICs are sensitive and they can be damaged by the soldering process
I watched your whole video and read the 49 comments before mine. I think it took guts to record everything and leave in your mistakes, it will probably save some noobs from making some of the same ones. As far as it is a bit sloppy, that's more of a personality thing, as long as you're happy with it, that's cool. I love that you just attacked that bish and made it your own. And like you said, it's a homemade one and it's going to look the part :D The only thing I could add that hasn't been mentioned yet is that you didn't have to struggle so much with that LED, and even change the height of the foot switch. Just attach some wires and put it where ever you want.
Nice man , very helpful. I like that you gave a list materials at the beginning also !! I'm thinking of doing a DIY guitar just haven't decided which model yet. Strat , Les Paul , Flying V. I may do all three !!
Unfortunately I've been too busy with work for the last few months to build and film anything of interest. Really wish I had more free time but I guess paying the bills comes first
This pedal has outlived the Ibanez TS and OD line hands down.. It truly is the desert island pedal of all time.. It is so versatile and Amp friendly it's ridicules..
since this the first video of yours i watch it was very informative and very educational for me since i have never done anything like this before it’s not easy but not that hard either thank you very much for posting these kinds of DYI videos especially for a beginner like me now fortunately for me i have a good friend i’ve known for about 35 yrs that is a wiz at stuff like this that can help me he mods stuff all of the time even amps and i must say that rat pedal clone sounds pretty decent i’m looking forward to watching your other videos on the tube screamer and the over drive and i hope that was red paint on your left palm and not blood lol at the end of your video
Thanks! Yeah just paint hehe. Unfortunately I lost my workshop space so I'm currently looking for somewhere new to work out of. Any more pedal builds are going to have to wait until that unforunately :/
Late to the party but the original op amp was the lm308 (I think) which is obsolete. The direct replacement is the OP07 which is also obsolete. This seems to be one of the few pedals where the op amp does seem to affect the sound/tonal character of the pedal. It's hypothesized that the poor slew rate of those op amps may be what gives it it's character. The TL071 will probably sound noticeably different. Distortion pedals usually use little current and a 9 volt battery will last a long time if you prefer going that way.
LM308 is still available. I swapped out 4148 diodes for red leds as someone suggested to me for better dirt, and maybe drill holes in the case for red eyes if they do light up. Might also do some of the “Mightier Mouse” mods (Beavisaudio).
I built one in my "Sensors and Signals" class in college. Now that I think about it, it might still be in my old desk drawer because I forgot to take my breadboard home the last day of class. 🙄
Are you running a compressor or is that distortions natural compression? Ive been looking to build a Rat pedal but havnt found the parts till now so Thank You
On the legs I think 2mm is industry standard. I like to clean the board with a soft toothbrush and isopropil alcohol. Easy to see cold joints or bad joins. Bet good work.
Hi, why did you use a TL071? better use a OP07 like rat II, this one doesn´t use the compensation capacitor neither. Original is LM308 which uses comp cap.
Yeah, the guy was like "you need to make sure you write down where the dot is". Like the socket wasn't built in a way that avoid this problem. And the guy simply did this writing WHILE being worried about that. If anyone wants to change the op-amp in the future there is a GIGANTIC chance they'll put it wrong
I have built Tayda pedals before with success. I’m on my second Tayda Rat and although I get a straight signal through it when I turn on effect I get nothing but a lit LED. Any suggestions for troubleshooting?
Do you have to have the stereo output jacks, or would mono jacks suffice? Only asking because the mono jacks are a fraction of the price and the stereo jacks are out of stock at Tayda :(
One stereo input jack is only needed if you want to use a 9V battery. Plugging a cable into it is what arms the battery. If you're going to run your pedal off of power, then mono is fine!!
If i buy two jacks, Footswitch and box I'm already over 30 euros. How on earth can you get them so cheap. (Note tayda ain't an option where I live but still if not buying in bulk I can't get those prices anywhere) (Let alone with custom pcbs)
I haven't looked in a few years but Tayda was exceptionally cheap for me when I made this video. Digikey and Mouser sometimes had decent price options but Tayda was by far the most affordable
I know Capacitors have a positive and negative side, is this so with the Resistors? I see the coloured bands around them, they mean something? Does it make a difference which way they are inserted into the board? Thanks by the way, i don't understand why this has only had 9448 views? I will be sharing the link, thanks again Baldur. I'm subscribing bro, when i get my channel up and running hope you'll pay me a visit. God bless.
Resistors are not directional. The stripes on resistors indicate their resistance, it's too much to explain in a comment but google can teach you to read them.
Hi to you. You had a printed pcb and just put the components in the places and soldered. But many like me don't have access to this pcb. Please draw a circuit diagram and show exactly how the components should be connected. Thanks Buddy 🙏
I do not know if this is offtopic, but you could have it all in tonepad web. Circuit diagram, components, pcb to transfer, how to put them... it is an old web but it still works.
Have you tried other chips in it yet? I had a 308 originally and was loving the sound, but I accidentally bricked it when I put it in the enclosure (long story). I put in the same chip you have and I did not enjoy it as much. I'm going to try a 741 chip and see if its closer to what I want based on what I saw on the diy pedals channel vid showing how close it came: ua-cam.com/video/l0qVnxUJwsw/v-deo.html I'm hoping it isn't just my imagination that it sounded better hahaha. I do know though that a CA3130 sounded better to my ears as well (its what is in my pedal currently, from before my research I did today)
0:00 me: “yay, building ‘my own pedal’ from scratch” 1:14 i need to buy a PCB and assemble the circuit…? not really building anything from scratch, is it? the anticlimactic opposite of creative.
Why do these videos say build your own and then it's just putting together a kit ? No wonder there are no new circuits and everyone is just putting together clone kits
You want somebody to breadboard a brand new never heard before circuit, design a pcb, have it made, test it, correct it then show them ordering components then put it together? Haha. What he’s doing is definitely “building his own” Rat my dude ;)
Obviously you are lacking any sense of precision in your building effort..... well, if you are happy, that it works at all, that should be fine however. For me looking at your drilling of the holes, in the roughly approximate position they should be in, was painful.

I agree, there aren't enough DIY pedal videos on UA-cam yet.
I'm just getting started doing this on my channel.

I bought my Proco Rat 2 for $40 a few weeks ago. But this is great content to learn. But it's amazing how cheap you can find guitar pedals.

I saw the “Mammut” sign behind you and was reminded of Airwaves shows. Hopefully going this year. Cheers!

planning on making a fuzz face with a rat tone stack and a bias trim.
Thank you for making such a great informative video. I’m looking forward to building.
I bought mine from Wuhan several mos. back for 28.00 fully built included shipping and it was sent me as gift
Tayda has a drill template for the pedal housing, comes in their build list
Thank you so much for this!
I built one in my "Sensors and Signals" class in college. Now that I think about it, it might still be in my old desk drawer because I forgot to take my breadboard home the last day of class. 🙄
Great video..i hope you do more pedal making videos..what would be the easiest guitar pedal to make? Simple easy? For my first time.
Are you running a compressor or is that distortions natural compression? Ive been looking to build a Rat pedal but havnt found the parts till now so Thank You
Parabéns pelo projeto, o amplificador que foi utilizado foi você que montou, tem vídeo sobre ele. Obrigado sou do Brasil
we want more!
What would happen if I swapped out the film capacitors for tropical fish?
how would I be ablt to convert this into a turbo rat?
On the legs I think 2mm is industry standard. I like to clean the board with a soft toothbrush and isopropil alcohol. Easy to see cold joints or bad joins. Bet good work.
Hey where can i find those style of knobs?
You've just inspired me to build a rat pedal for bass. What diodes,transistors and pots do I need for bass guitar?
very nice Iceladic accent, and a great video :D
takk🥸
Hi, why did you use a TL071? better use a OP07 like rat II, this one doesn´t use the compensation capacitor neither. Original is LM308 which uses comp cap.
OPO7 all the way
ua-cam.com/video/QfwpClT_26E/v-deo.html
Would you recommend this for an absolute beginner?
@Everett Angelo And still having a girlfriend?I think you will see it with binoculars.
For an absolute beginner maybe the 1 knob fuzz: www.taydaelectronics.com/pcb/one-knob-fuzz-diy-pcb-guitar-effect.html
Why did you install the op-amp socket upside down ? IT also has the cut out as marked on the silkscreen on the board to indicate pin 1...
Yeah, the guy was like "you need to make sure you write down where the dot is". Like the socket wasn't built in a way that avoid this problem. And the guy simply did this writing WHILE being worried about that.
If anyone wants to change the op-amp in the future there is a GIGANTIC chance they'll put it wrong
I have built Tayda pedals before with success. I’m on my second Tayda Rat and although I get a straight signal through it when I turn on effect I get nothing but a lit LED.
Any suggestions for troubleshooting?
Do you have the schematic?
What about doing the artwork?
That is the hardest parts.
Do you have to have the stereo output jacks, or would mono jacks suffice? Only asking because the mono jacks are a fraction of the price and the stereo jacks are out of stock at Tayda :(
Mono is fine!
One stereo input jack is only needed if you want to use a 9V battery. Plugging a cable into it is what arms the battery. If you're going to run your pedal off of power, then mono is fine!!
If i buy two jacks, Footswitch and box I'm already over 30 euros.
How on earth can you get them so cheap.
(Note tayda ain't an option where I live but still if not buying in bulk I can't get those prices anywhere)
(Let alone with custom pcbs)
I haven't looked in a few years but Tayda was exceptionally cheap for me when I made this video. Digikey and Mouser sometimes had decent price options but Tayda was by far the most affordable
How much for you to build me a Gonk? 🤔

Do you sell a DIY Rat?
Hi to you.
You had a printed pcb and just put the components in the places and soldered.
But many like me don't have access to this pcb.
Please draw a circuit diagram and show exactly how the components should be connected.
Thanks Buddy 🙏
I do not know if this is offtopic, but you could have it all in tonepad web. Circuit diagram, components, pcb to transfer, how to put them... it is an old web but it still works.
Rock it before you box it. 223 means 22 x 10^3 pF = 22nF.
Have you tried other chips in it yet? I had a 308 originally and was loving the sound, but I accidentally bricked it when I put it in the enclosure (long story). I put in the same chip you have and I did not enjoy it as much. I'm going to try a 741 chip and see if its closer to what I want based on what I saw on the diy pedals channel vid showing how close it came: ua-cam.com/video/l0qVnxUJwsw/v-deo.html
I'm hoping it isn't just my imagination that it sounded better hahaha. I do know though that a CA3130 sounded better to my ears as well (its what is in my pedal currently, from before my research I did today)
Not yet, just been sitting on my pedalboard recently - but I'd be very curious how it sounds with a 741.
I watch this as ASMR
Sounds like Rat!! Great video!
😃
The lighting makes your solder look black 😅
Blue oyster cult meets Hendrix
Sounded very basic... Real tat ic is different
ça sert à rien votre truc ,juste à consommer du data
0:00 me: “yay, building ‘my own pedal’ from scratch”
1:14 i need to buy a PCB and assemble the circuit…? not really building anything from scratch, is it? the anticlimactic opposite of creative.
its for learning how to make one. i know its kind of clickbaity but if you really want to make your own pedal, this is a great way to start
@Idk-hg8jr especially if you are of an inclination to monkey around a bit with the values to see what kind of sounds or happy accidents you might get
Why do these videos say build your own and then it's just putting together a kit ?

Mf thinks we're all jimmy neutron to come up with a brand new design from scratch 😐
Feel free to show us your pedal designs ?
Obviously you are lacking any sense of precision in your building effort..... well, if you are happy, that it works at all, that should be fine however. For me looking at your drilling of the holes, in the roughly approximate position they should be in, was painful.
I'm a hobbyist building a pedal for $27 so yeah I didn't stress too much that my holes were misaligned.
Or get a Rat for $80
I’ll take the DIY version, cheaper and much more rewarding
I am from the future. 27 dollars don't buy shit!
😢
