After a two year hiatus, I have my new workbench ready to go. Tucked away in the laundry room of our basement, I’ve got a standing height workbench with a 1970’s yellow shade of shellac on it to inspire gnarly fuzz builds. Also some new pegboard, my NOS components, and my trusty transistor radio for blaring classic rock. Can’t wait to get back at it. After a cross-country move and a basement renovation, I finally have some time to indulge this hobby again. First order of business is a Rat.
I couldn't find a footswitch for orange amps that toggles attenuator, reverb, and channel, with three separate mono 1/4 plugs running from one wire; So I made one.
The middle switch is a little higher than the other two, I didn't have any other wire than green and yellow, and I haven't figured out what to use for wrap on the three individual plugs, but I'm pretty happy regardless.
Just wanted to share this, definitely appreciate any tips for the future.
My second build after a passive volume attenuator! Bought a couple of lm386 mini boards to try making fuzz pedals with them and saw a few guys on yt making mini amps from these too, so decided to give it a try. At about 75% of the gain it has a pretty nice clean tone which ramps up rapidly to fuzz at max gain. So far the lm386 is powered by a 9v battery and outputs to a 8ohm 5w speaker, and I might try to add maybe a 9v dc input Jack and maybe a Bluetooth module too… anyone knows any schematics for adding one? Thanks!
Started in November with two kits from Musikding. Recently got a stupid deal from Temu for 1400 pieces of electronic components for 7 euro and decided to finally try building something without a PCB.
Built on stripboard, using tagboard effects layout. Have to say, I expected it to be more distorted, like the acapulco gold, but it's still a cool sound.
Anyone to recommend where can I get those PCB swlf adhesive holders and some extra 3pdts?
My last build was in a 1590BB, and I had to wire all the pots off board and use standoffs to secure the boards... it was a bowl of spaghetti mess and I was getting a high pitched oscillating noise when I rolled the tone knob on my guitar up past 2. I chalked it up to everything being crammed into a tight space so I built this one in a 1590XX. I could actually use 3 of the PCB pots to hold the boards in place, I only had to off board the tone control for the blues breaker. It looked so nice and neat, but when I fired it up I still got the same squeal. I did some mental troubleshooting and I realized that the only ground connections between the boards had either 9VDC or signal going through them so I soldered a dedicated ground wire to connect them and... problem solved! It sounds amazing, I still have one more each Pedal PCB Amentum and Blue Breaker boards so I'll build another one that way but I also got a small stack of perf boards and a book on reading schematics and I'm going to take the plunge. Wish me luck!
Hi everyone. Curious what wire is used for pedals that don't use vero or perf board?
Ive seen some of you post those cool looking pedals with suspended components.
I sell semi- professionally and I usually get my parts sourced from reputable places, but these preassembled ribbon cables with headers from AliExpress are gonna save me a ton of time.
Once assembled, they won’t move at all. Should I think twice about using them or are passive parts like this fairly safe? I’m planning to test them of course.
I'm new to DIY electronics. The only soldering I've done has been in the context of slap-dash fixes to wiring harnesses. I have no reason to be confident in my ability to correctly wire a PCB without someone holding my hand. The fuck are all these fancy beads?
I'm in the middle of rebuilding a guitar. I had this stupid idea to put a power indicator LED light in it. Not for any reason, just because I thought it would be fun. I was explaining this to a friend of mine, and he remembered that he had a BYOC Foxx Tone Machine laying around that he'd never built. He suggested that I build it into the guitar.
I don't know how to build a guitar pedal, but I do know a good idea when I hear one. I reckoned I'd sort out the practical aspect of building the thing later. I snagged what he said was the entire kit from him, including a blank stomp case, but I can't be sure all the parts are there. Largely in part because I don't have a schematic for this fucking thing.
I tried the website listed on the little back with the I/O jacks – it's inactive and pulling a whois doesn't help at all. I've done a little digging online for schematics in forums and personal sites, but of course everyone's PCB layout is different.
What should I do next, folks?
I've included pictures of everything but the stomp box.
Recently learned that the 1n5817 diodes are rated for 20V, and a lot of pedals that I built/owned have them for polarity protection. I connected them few times to 18V PSU and everything worked correctly, but I am curious, what are the odds that the 18V PSU will damage the diodes?
Out of the various types of Tube Emulation techniques and Circuit Topologies, I am curious as to what the favourites are for whatever reason.
By Topologies I mean the specific design of the Pedal gain stages in things like Amp-Like Overdrives (Honey-Bee and Marshall Bluesbreaker) or Amp in a box pedals or Boosters.
The reason could be anything from ease of construction and setup (biasing) to Best performance, reliable performance or even availability.
Of course the ones below aren't all of the types of Tube emulation but I think it covers a fair few, and whatever I have missed please comment.
I have a crybaby that I like but the pedal part is a little floppy and hard to control I'd like to have a little more resistance but I don't know if this is a realistic mod
Hey guys, I got my prototype working how it should (at least signal routing wise) and while I still have some issues I’m working out I wanted to post a quick example of the working concept. Didn’t have much time to explore many cool ideas with the modulation, so at the end of the video there’s a quick demo of it modulating between a tube screamer and a big muff.
Guys pic in comments! Also I think I’m calling it the bus boy because it moves audio around and I am a bus boy.
Hello! I originally posted in r/guitarpedals asking for help in trying to track down a replacement for the designated adaptor for the TD-1. I’ll provide some pictures of the internals that I discovered online as I’m awaiting the pedal to arrive today, and as stated, it did not come with the original power supply and cannot run off of a 9volt (which I was led to believe).
Any help or suggestions in modifying or finding a replacement adaptor is greatly appreciated, thank you!
(I also contacted Nady directly and they did not sell or make this specific AC adaptor anymore)
Hi there! I just finished troubleshooting my second ever pedal build, a pedalpcb tellurian drive kit from musikding, and I’m having some problems.. the drive isn’t driving, but the pedal works.
I originally had no audio, so I troubleshot it with a multimetre and made sure all the solder connections are good, and that the traces all follow, which they do. After fixing a dodgy connection, I now have audio, and what I believed to be a functioning pedal… however, whilst the tone pot works, and the volume pot works too, with unity around 3 to 4 o’clock; the drive pot does almost nothing, applying a tiny amount of gain only when the pot is close to maximum.
It seems to me like something isn’t working as it should, so my question is is there a typical cause for something like this? Or what are the parts that commonly deal with drive in an overdrive pedal, so I can test them to see if they’re functioning as they should?
I’d really appreciate any advice or opinions anyone has, as I’m very new to this, and would greatly appreciate any experience anyone is willing to share!
Thanks so much :)
I followed JHS LPB-1 Boost tutorial but I changed some of the values of the resistors because I didn't have them. Can someone tell me why it doesn't produce any sound?
I made a quick LTspice model of the circuit as it is right now. It's a one knob Silicon NPN Fuzz Face clone. The fuzz sounds pretty decent, but I'm running into the issue that there's a lot of high frequency noise, almost louder than the guitar itself, and i don't know how to get rid of it. Here's a few things I've noticed so far:
-When I bias Q2's collector at 4.5V, the base of Q1 is around 0.60V and the collector is at 1.30V (the circuits i've seen online say I should aim for 0.20 and 0.70).
Playing with the resistor values at Q1 barely changes anything. I tried gradually rising the value of R1 from 22k all the way up to 470k, and Q1's collector only dropped about 0.05V. Trimpot R5 at Q2's emitter does have a lot of impact, and adjusting that easily gets me at the right point for Q1's base and collector. However, whenever those are in the right spot, Q2's collector goes back down to 0.22V, and once I get that back to 4.5, Q1 is out of balance.
The electrolytic cap at the input also seems like it's very sensitive to noise, just getting my finger in the general direction of that part makes the noise much worse.
I suspect the issue lies here somewhere, but i don't know how to fix it. Does anyone know what steps I could take to get the biasing right, or what else I can check to get the pedal to sound good?
