Ok, you got your soldering iron and nothing is going to hold you back, but you have no clue where to start or what to build. There were others before you with the same questions... read them first.

I've done quite a bit of searching and haven't been able to find anything that solves my problem. Hopefully this post isn't redundant.
I just quit smoking and so I decided to start building pedals so I'd have something better to do than pacing around the house and cursing the day I was born. I have a pretty solid understanding of electronics, but I'm sort of stuck.
The problem I'm having is, even when I filter my input power, there's so much noise that I wouldn't consider any of my builds so...
I am currently building my first pedal and have ran into issue, I can't get my audio jacks to work. There is a lot of noise when I unplug them, but as soon as either of their wires touch, red or blue, the noise cuts out. Below is a picture of my audio jack, if that helps you figure out the issue. The red is the input/output and the blue is ground. If anyone could help me out, I would greatly appreciate it!
So I built the Landgraff Boost on stripboard last night thanks to tagboardeffects and used their offboard wiring diagram as well. The pedal works wonderfully in effect mode and sounds quite good but switching it to bypass mode mutes the signal. What's going wrong here.
FWIW, this is my fifth stripboard build and I've used that same offboard wiring diagram on my other builds and its work great.
hi, i was thinking about freq in guitar but im not sure about i, i mean for example highs, mid or bass, if i ant to set a filter for each freq, what would be the setting freq of each???
As far as i am concerned - it's a diode with photoresistor. I have seen people making them from diode and photoresistor elements.
But what should i take into consideration when chosing them for a optocoupler - ?
Will standard (on off red light diode) be ok? How to chose the photoresistor basing on On resitance and OFF resistance of an optocoupler datasheet?
This is for the McMeat clone.
Hi everyone, new here and this will be my first pedal build... The circuit I want to build is on a Radioshack IC PC Board (276-159) and I want to transfer it to vero to see if I can shrink the physical size circuit down. Trouble is I have no idea how to do this! I have soldering experience but only with guitar circuits - not pedals (yet!).
It currently looks like this... This view is from the top, components facing up, traces facing down. I cant figure out how to embed it right now but will...
First of all, I am a newbie. Let me dispel any myths anyone might have about my abilities.
I've spent a good amount of time reading books and articles and this forum about how to build, solder, etc.... and have attempted to build the janglebox pedal 3 times (at least) none of which ever works (obviously). After the last attempt, I put down my soldering iron and walked away for about 4 months because I was so frustrated. Now I'm returning hopefully with renewed enthusiasm and hunger.
How do I decide how to space the drilled holes on the enclosure?
For example, what is a typical distance in between the holes for the knobs, the distance of the footswitch/knobs from the edge of the enclosure, and so forth? What are some standard measurements and layouts of typical pedals such as MXR in one, two, three, and four knob layouts?
I recently acquired an fl305. The previous owner had attmpted to convert it to use two power supplies rather than batteries and I want to convert it back. I dont have the right power supplies so haven't been able to test it so I don't know if it even works. I haven't been able to find a schematic or a guts picture clear enough to show which wires should be attached to each battery. The best picture I have seems to show the #10 and #12 wires to one battery and the #9 wire and the ground wire...
I've been afraid of drawing layouts for some time, so i choosed a simple circuit to start. But since i'm a begginer i do not feel certain that everything is ok with this one.
I know i could tighten the layout, but for know i just want to know if i made some mistake or not. And i would prefer to know that before building the circuit :roll:
Is this normal? I am not sure if I am doing something wrong. My problem is that the epoxy on the lugs melts and the lug falls out before I can heat it up enouhg to get solder on it. My solder seems to need a bit more heat than normal (350C) to melt in the first place though and I'm wondering if that is the problem? Do I just need solder that needs less heat, or do I need new switches? Every one in the batch I got has done the same thing.
Hi all,
I am attempting to build a tonebender mkII following this great schematics
So far I get nothing, but that is usual ... I will start looking for errors once I get the icl7669s- the one I was using went to other pedal.
I have a bunch of soviet transistors GT1323 and GT1322, any points how to select 3 of them are appreciated.
the hfe;s are grouped : below 100, around 150, around 240 and over 350....
So this is my first post... that considered I don't really know if this thread belongs here or in the Switching & Wiring section.
I want to build a 2 in 1 pedal, one side a SHO Clone Boost... and I'm afraid that's the easy simple bit over and done with.
Then there's a 2 way toggle to switch between this SHO Clone, and a pre-amp/boost. I made a flow chart below to illustrate how I ideally would like this pedal to work and have also attached a photo shop mock up to add a sense of realism to the...
I am trying to make this one work.... I have no signal at all.
I tried to follow the signal with audio probe.
I have signal at the b leg if the 1st transistor, but nothing on the C.
As I;m not quite sure how to determine if a transistor works OK I tried changing the one there but still no signal comes out.
other than faulty transistor what else could cause this?
also what voltage should I read on the transistors pins?
Can somebody explain, to a beginner, what exactly is happening when you have a resistor in a circuit that bleeds to ground vs just passing on in series with rest of the circuit
This is in reference to the sdd-3000 schematic here
For example, R4 bleeds to ground, but right after it R6 is in series with positive wire. Why?
What is happening with the electrons when you bleed a signal to ground through a resistor as opposed to having it continue one?
Hey, here is a noob question. I'm currently just looking at making some simple transistor based circuits (a clean boost first) and at the same time I'm trying my best to really learn about transistors from an engineering perspective.
Something has me a bit perplexed though - what is the general MAX current/voltage output of a stompbox? How do I know where to set my limits? Obviously I don't want to be spitting out +/- 15V swings, but what kind of range am I looking to use? Obviously some...
Hey guys!
I am making my first stompbox and I have a couple questions.
First of all, here it is!
My first question is should I put the teflon washer that came with the switch on top of the case or under the case.
And my second question is about the 3pdt switch wiring. I have a little board to easily break out the wiring but after checking the wiring diagram I believe that this board only allow ungrounded input. The red arrow show on wich side of the switch the CHK logo is and I...
Hi,
I'm building a fuzz, the schematics calls for a 2k biasing pot, however I don't have one.
My question is can I use a normal external pot instead ?
and closest thing I have is 5k actually c5k which is anti-log?
Hey guys - I'm brand new to this forum and an absolute beginner when it comes to building stomp boxes. My question: looking at a schematic that was listed on this forum under the jangle box
and when I opened the schematic, there is a little section of the schematic at the top of the page that is not connected to the rest of the diagram. How do I read it? In other words, when it is not connected to the rest of the diagram/schematic, how do you know where it connects to the rest of the...
I am about to buy a used Morley Wah Pro Series like this for cheap:
I want to put a Tremolo circuit that is already built (Tremulus Lune clone from Musikding) into it ,after removing of the wah circuit, to adjust the speed of the effect with the treadle of the Morley.
The sweep mechanism of the Morley is an optical LED+LDR circuit, and I'd like to fit it in the tremolo circuit or wire a new one to replace the speed pot of the tremolo.
I've decided to try building a Colorsound Power Boost for myself after reading this thread:

Hello, absolute newbie here. I just finished my first build using this schematic:
I got audio but it sounded horrible. I checked for unwanted bridges, bad solder points and bad components and couldn't find any faults. I was wondering though - would it be possible the bad quality of sound stems from the fact I only ground the pot I was asked to ground (Volume)? Should I ground all the pots? Everything else (jacks, DC) is grounded.
New to DIY pedals and am considering getting the fuzz factory clone
from Poodle Pedal Parts. Just a few questions so sorry for the
noob-ness!
On wiring common ground, do all of the ground connections go to a single
point? (Sleeve of input or output jack?) including the ground on the PCB? Can
I tack these wires to a single piece to then connect to the sleeve?
I was going to use sockets to install the Ge transistors. Is this a bad idea
I am concerned I will fry them (I do have soldering...
I am about to order the parts for my first build, an EP Booster clone. This is supposedly an easy build, which is good as I have zero experience in building electronics.
After some research, I have decided to use this veroboard schematic.
So far I think I have done a decent job at translating the layout into a parts list, but I wanted to run it by those more experienced to make sure I don't miss anything.
