R.A.T HELP

First build.

R.A.T from Jeds Peds

Had a glowing resister as I had it plugged into 18v by mistake ( idiot I know) Checked with multimeter and it's still reading the correct resistance.

Had diode wrong way wrong and corrected it.

Now when plugged in a testing it is making a quiet high pitched ringing.

Any thoughts ?

Fuzz pedal recommendations

Hello all! I've made a handful of pedals with mixed success, and need some recommendations. I have a coworker I would like to make a pedal for as a Christmas gift.

I've made a couple of fuzz pedals but never thought they sounded good enough to really box them up. I'm hoping to find something relatively simple but usable that sounds good enough that someone might actually use it. I've used primarily vero board/strip board for my electronics diy so if possible I'd like to use materials I have.

This coworker is not a very good guitarist per his own admission, basically a middle aged guy that indulges his inner teenager and doodles around trying to learn chords and buys guitars (I'm sure y'all know the type). It doesn't need to be a gig-worthy pedal, but I'd like it to be something he enjoys mucking around with in his living room. Basically a gesture that says "hey man, it's been really good working with you this year". I know the thought would mean a lot and I want to put a smile on his face.

I have a stock of plenty of common parts, but I would prefer not to have to hunt down any crazy obsolete boutique things. I have a handful of enclosures of a couple different sizes. I have plenty of resistors, caps, pots, knobs, stripboard, etc. I don't mind slapping together three or four simple builds and testing to see which one I'll box up. I haven't been soldering much this year due to working overtime like mad but spent the prior two years building some pedals and synths and built a couple amps so I shouldn't have much issue putting something together even if I have to lift some traces to get back in the swing of things.

Thanks to this community, and happy holidays to all!

Atypical enclosures

I want to know if there are sites offering different enclosures than those we are used to seeing. Otherwise, tailor-made.

I want to make very original pedals

Big muff pi kit - farted out and now silent when active. Pease help me troubleshoot!

Second pedal build - this one is a Big Muff Pi "Muff'n" kit from guitarpcb. I built the "civil war" variant. Lights come on and switch red/green as expected; When switched on, initially there was sound for a few seconds, but it was choppy and farty, then I quickly lost sound when playing the higher strings (bass guitar), then finally E string cut out completely and now it's silent. Pass through continues to work fine.

I'm fairly new to troubleshooting and I don't have an audio probe but I do have a regular multimeter. Any ideas for where to look first? Does this sound like a fried transistor or diode, and can you talk me through how to test specifically? Attaching shots of the pcb and schematic. Thanks!

Recommend size for enclosure?

I just got my first pedal done and I think it sounds sick. It’s a boost so it’s nothing special and only has one knob and I plan to add a stomp switch and I will probably order that with the enclosure. Anyway it’s a copy of of the Lpb-1 but I still really don’t have any idea of what size enclosure should I use. Should I print the pcb first then decide on an enclosure size? If I do that it make take till next year cuz I’m going in holidays. Any help is appreciated

Is it possible to add a footswitch to this life pedal clone for the octave?

This is the pcb I want to use. I don't need a boost so I prefer this pcb to others, but unlike the other clones, this one doesn't have a footswitch for the octave. I guess I could also just stick a green ringer and rat clone in the same box, but I'd rather not.

Replacement parts for DIY Treble Booster

I am following this diagram:

https://preview.redd.it/7rhmnkmt9c7e1.png?width=4080&format=png&auto=webp&s=ff0045eef04f7b8c48554f2223967a6a8422002d

With the 9V transformer, it is around 80 USD in materials besides the veroboard and wires I already have.

I could not find the exact component, but I found these:

  • OC42 PNP transistor

  • Sistance: 10K ohm Edit

  • Electrolytic Capacitor 47uF 500V +50%-10%

  • Carbon Film Resistors 1 Watt 3.9K ohm

  • Carbon Film Resistors 1 Watt 470K ohm

  • .022UF Tone Capacitor

  • .047UF Tone Capacitor

  • Medium Pedal Enclosure

  • Soft Click 3PDT Footswitch

  • Tip Switch, On-On DPDT

  • 1/4" Stereo Switching Jack With Metal Ferrule

Would that work?

When the sun explodes inspired feedback looper?

Hey y’all. Familiar with Beautiful Noise When the Sun Explodes? The momentary feedback is one of the coolest functions of that pedal. The website says “The feedback footswitch engages a linear rising or LFO/tremolo controlled feedback loop, which forces the wet reverb signal back into the input creating some over-the-top noise effects.”

My question is whether or not a simple feedback looper could be built with a momentary switch and a similar linear rising/lfo setup to feed every pedal in your chain back into themselves in a similar way. Feel like this would produce really cool results with delays obviously but even cooler sweeping pitched feedback with fuzzes and distortions.

Simple guitar/bass pedals?

So I'm an engineering student and I have a project which consists on making a device that combines electronics and music, naturally, I wanted to make something that I could use with my bass, and I thought that some simple bass pedals would make a great project.

I'm looking for schematics/tutorials/documentation for any really kind of pedal, fuzz, distortion, delay, octave, all are more than welcome.

My objective is to try and make more than one pedal, as to present a more varied project.

Thanks in advance for your aid and time 🙏

(possibly stupid idea) Analog rotary speaker pedal using spinning LEDs?

This is probably way beyond my ability to create, but I'm curious if it's feasible at all. I'm imagining a rotary speaker pedal that employs LEDs attached to small spinning motors, with strategically placed optical sensors on the perimeter (photodiodes? LDRs?) So it modulates amplitude and pitch (Doppler effect) as the LED spins by the sensors. There would be two of these units to represent the Leslie's treble and bass speakers, spinning at different speeds.

What do you think, worthy idea or nay?

Spring reverb made with motors?

Just checked the video from LMNC and was wondering if someone tried making one?
Would look to hear more for inspiration as I would like to build one myself too!

CD4047 behavior

Pin 13 is the basic frequency obtained by the resistor and cap across pins 1,2 & 3.

Pin 10 (Q) and Pin 11(Q) shows the half frequency of the original frequency at pin 13.

Both frequencies at pins 10 and pin 11 are inverted to each other phase. The inverted Outputs are 180 degrees out of phase.

So why is it that Pin 13 has a lovely square wave around 3kHz but pin 11 is the same as 9+ and pin 10 is the same as GND.

Resistor is 10k and Cap is 180nF.

I've tested 3 different ones, so either they're all bad or I'm dumb and I think the latter is more likely lol.

Offboard wiring - wiring in a 3.5mm headphone jack

Using this diagram, how would I wire in a simple switch to change the input from guitar signal to 3.5mm headphone jack? I'm building a test box and I'm want to use the headphone jack to provide a signal for the signal probe.

Question about the Boss DS-1 circuit schematic

Hello everyone!

Lately I've been studying some distortion pedal circuits and I've come across a detail in the schematic of Boss DS-1 that really confuses me. ElectroSmash provides a great analysis of the circuit but even after reading it I can't seem to understand what is going on.

The issue is in the op-amp gain stage with the diode clipper. From my understanding the input signal is amplified by the op-amp which also introduces a DC offset of 4.5V due to the virtual ground, is that correct? Then, at the output of the op-amp we have the diode clipper which is connected to 4.5V, hence clipping the signal when it exceeds the limits of 4.5+/-0.7V, right? What bugs me is the capacitor C9 which is in series with the output of the op-amp... Now, wouldn't that just remove the DC offset of the signal? Thus, shouldn't the diodes be connected to ground instead of 4.5V, to clip the signal beyond +/-0.7V?

I thought this was a mistake, but I looked up other schematics (like this) of the circuit which confirm that this is indeed the correct configuration (additionally the C10 capacitor seems to also be connected to 4.5V, which may actually be a mistake on the ElectroSmash schematic?). There's probably something that I'm missing or I don't understand correctly, I hope that someone could offer some insight.

Thanks a lot in advance!

Best delays to build ?

  1. For DIY there 2 options Analog Style Analog BBD and Tape Style Analog BBD ?
  2. No way to do Shimmer and Tap Tempo, Reverse and other styles ?
  3. No one does String Tanks and Tapes Now ?
  4. Recommend me some schematics. I found these -

I found schematics for these -

  1. Boss DM-2W
  2. MXR Carbon Copy
  3. EHX Memory Man

Other analog I know for which I couldn't find schematics -

  1. TC Electronics Flashbacks
  2. Uaudio Starlight Echo Station
  3. Retro-Sonic Analog Delay

Tape Style Analogue, No Schematics

looking for a good pedal tech in the U.S. that does mods

I have a Black Arts Toneworks Destroyer. for those that aren't familiar, its a 2-in-1 pedal with a bypass switch for each circuit - on one side is the "Oath" (a Marshall flavored preamp clone), and on the other side the Ritual (a high gain fuzz). it has just one output volume knob that only controls the Ritual side. the Oath side of the pedal is hardwired on 10, and it is insanely LOUD. so, what I'd like to do is have it modded to add another output volume knob for the Oath circuit, and a switch where you can change the series order of the circuits. can anyone recommend a really good pedal tech that can do that?

Implementing germanium diodes into fuzz face

I need help adding russian germanium diodes into a diy fuzz face build. I was originally going to use them as clipping diodes but I havent had desirable results. Id still like to have them in even if its not typical clipping. Can anyone lay it out plainly to me as to how and where I could work these into an NPN fuzz face? Thanks

Help building first clone: Land Devices HP-2 (Also where to source parts in Canada)

https://preview.redd.it/2or0i6yjh57e1.png?width=2354&format=png&auto=webp&s=d48591476ff436e4d3ab037d29049048c695182f

Hi all, long time lurker, first time poster.

Was in the shop the other day and came across the Land Devices Harmonic Percolator 2. It's a rad pedal, but is around $500 CAD. So it feels like the exact right time to try my first build.

I'd like to try breadboarding the thing first, and then if all is well, move it into an enclosure.

As this is my first go building a pedal, I'd very much appreciate any help answering some of my assuredly basic questions.

I watched this video which has gut shots and a breakdown of the Land Devices circuit. They took the schematic of the original Percolator and updated it with the Land Devices version (see photo)... but I have questions:

  • Why is there no R5, C5, or D1 in the diagram, but there is a R6, C6, and D2, etc? Don’t part numbers have to be sequential?
  • He mentions 220 µF Aluminum Electrolytic Filter capacitor, and a 47, in the audio, but would that need to be reflected in the diagram? there's another video of this schematic where someone comments: "There is a high frequency bypass cap missing that will diminish the highs but also prevent self oscillation at full gain. The diagram is not clear on connections or non-connections." So I'm wondering if that youtube comment is the solution to the missing C5?
  • From the video and schematic, I've made the attached parts list. Does anything seem to be missing?
  • Where the devil do people source parts in Canada?

Thanks for any and all help
