Hey! Thanks brobro always nice to hear you like the video 😀

I'm enjoying this series on the LM386 opamps. Got some myself and am experimenting to see what sounds best. Definitely going to try this out. One thing I'd love to see in your future videos if possible is if you could put a circuit diagram alongside your footage. Would be really helpful for showing exactly what you're putting together so people like me could replicate your experiments more easily.
Super cool experiment. The last few to me sounded the best. A part of me wants to lean towards the red l.e.ds the Two different sizes together sounded pretty cool.
@@jameswitham3780 yeah I have experiment with that before but I don't think it would do much on a diy pedal like this were I can't control what frequency goes to what diode
In my opinion BAT41 is da best! I've tried a lot of different diodes and found other is giving more muddy sound. I hope you'll understand, english is not my native language ;)
Those diodes are wired in coring arrangement and not a clipping arrangement, so you're actually cutting out the middle of the waveform with those diodes.
@@zurowetz it was mostly me having a break down and you being overly patient with me lmao. Thanks again for all your help, and all the content you make.
@@zurowetz man you ever use those pt2399 karaoke pcbs and turn them into a pedal or experiment with those? I never seen or cam across a video where you have and I think it would be cool to see what you do.
@@madzpanda no I have never I have seen things about them but never played around with it myself but I'll get some and have a look thanks for the tip 😀
Try diodes on both outputs 1n4148 on second output and small and large LEDs on first output as a boost into the second stage and adjust the gains to create an interesting sound I'm sure. Perhaps add a sweep tone or tone stack
I neeed there to be a forum or Reddit on stuff like this. I got a Marshall MG50DFX and I need to modify it. The overdrive channel the gain comes on way to fast, but then never gets high-gain enough. And for the clean channel there is a “gain level” but it’s pretty much a volume knob, at 10 it’s just louder it, it doesn’t break up at all! I am going to mess with the resistors and clipping diodes on the overdrive channel but I’m not sure what to do with the clean channel. I am interested it making this a usable amp, I’ve though about adding a tube preamp and a EQ and building a box for it for it to be a little head.
Be careful messing around in a amp if you don't know what you're doing sounds like maybe you need a new pot for the overdrive gain remember that if you change the diodes in the clipping part ( if the amp uses diodes for cipping) the volume of the amp will change and so turn down the volume and slowly bring it back up so you don't blow the speaker/ your ear 🙂
Hey! You forgot to add resistors!!! I actually like the bridge resistors better than the normal diodes. I have not done it with weird resistors like germanium....would be cool if you show us! Also, do you have a diagram for your setup? Where was the black cable going to from the amp?
Im not sure I understand what you mean with I forgot the risistors but the black wire is the yellow clip on the jack its hard to see so sorry about that I'm going to rebuild the pedal part so there is going to be a new video on it soon 😊
@@zurowetz You tested how different diodes sound but you did not do MOSFET and transistors. You can usually short two legs and treat them like diodes. Nice! Looking forward to the new video.
I was able to build a little tester box like yours and it works great but I cannot get the LM386 chips to work! I’ve tried about 5 out of the 10 I have and they are all overheating and melting. What am I doing wrong?
Great that you made the box😀👍sorry to hear that you are having problems with the lm386 sounds like you are using too much power it's 5-12 volts and dc so make sure you are using the right power also it can be the impedance have you tried with a battery? If you think that's the wiring check the original video and compare with it good luck and keep me updated 🙂
Thanks! I am using 9V DC center negative. I tried both a DC plug that I know works and a 9V battery that I know works because I use it on other pedals.
@@ltcm5052 then it must be the wiring because I feel it would be hard to melt it otherwise 🤔 go through it again and make sure everything is where it is suppose to be and that nothing is touching something it's not suppose to
@@zurowetz I think i figured out my problem... should all grounds, including the output jack ground, be connected to the input jack ground? Sorry for the n00b question! lol
@@ltcm5052 im not sure I understand the question but there needs to be one ground to dc jack and on ground to in and one to out jack all the grounds on the lm 386 are the same just so you know if you have a enclosure for metal it can be used as ground then you don't need to ground both jacks only one or like i have it in the video were the ground gose from on jack to another ond then to the board 🙂
I never really made a video on how I made it but I have this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1pOY9KxltXU.html&ab_channel=zurowetz and together with this video maybe you can build one? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0uBH0CTIlFI.html&ab_channel=zurowetz
Hey man, Im struggling to get into the shed to make a vid of mine - you could try two boards in series (poor man's eqd) and then add clipping diodes to that?
Sorry to hear that I was looking forward to you telling me that you hade started making videos but I could make a 2 bords in series I have bin thinking about it already 😁
Maybe could see it like that but to me square wave is more synth like distortion like the ugly fuzz that I built last year this doesn't sound quite right to be square wave
why are you not clipping to ground thats they way its normally done all tho i know it can be done how you have it hooked up too its just not common. you would need a dc blocking cap before the diodes to stop DC getting into the opamp
It was just a experiment I never thought anyone would watch it but I was hoping to change the clipping and find something new and fun but now I'm thinking maybe I should have just put a cap on the lm386 to change it there 😅
@@zurowetz if you set it to clip to ground the LED would light up and it gives it a different clipping tone. you can add a resistor between the clipping diodes and ground to make it sound like soft clipping or straight to ground for hard clipping.
Ok I just took inventory of the diodes I have and here’s what I’ve got: 1N4007, 1N5819, FR107(?), FR207, 1N5399, 1N5822, a super tiny transparent red glass one that’s so small I can’t read it, and then some LEDs (red, blue, green and yellow). Which ones of these would work???
Anything can be added to Anything! But do you mean the LM or the diodes at the end? A ds-1 already have diodes and if you want to you can experiment with switching them out
@zurowetz Sorry, I'm new to modding/building pedals, that was a dumb question. I guess what I meant is, can the little blue pcb unit be added into a pre-existing circuit easily? Maybe I'll just start with a basic DS-1 mod, I emailed Small Bear Electronics a few days ago to see if they had any mods to suggest for a beginner with their parts.
@@scramblesthedeathdealer no its not stupid I just wasn't sure what you were really asking 😊 if you have the old ds-1 you could try to see if you can find a way to add it but I guess I would ask why because if you just want to make the ds-1 louder you only need to remove the diodes and nothing more so what is it that you want to get out of modding your ds-1?
@@zurowetz Honestly, I'm just looking for something unique sounding (to the Boss compact pedal line, I have OCD and only collect Boss compact or twin pedals, or Boss-shaped clones like PSK, JS Sound, etc) that will give me experience in soldering and modding/building pedals. My ultimate goal is to clone a Boss TB-2w Tone Bender, I missed out on one and it makes me sad every day 😭🤣 I also am thinking of building clones or variations of other pedals into Boss pedal housings. I have problems... 🤣
I am also interested in learning enough electronics engineering to repair pedals/amps (gotta replace a tube or two in my Egnater Tweaker 15 head, but concerned there may be another issue causing them to blow... also aware that amp capacitors can kill you 👍) maybe even my Panasonic CRT TV one day!
One cool thing you can try if you wanna is build two boost pedals one after the first and then put the kipping diodes on a pot to ground and have it on the out 🙃
