DIY effect pedals?

OK, soo, i would like to start making some effect pedals, i play synth, guitar, and sing a bit, what do you recomend building for a good starter effect? i am already into electronics, i have built a couple amps, an oscillator synth and some other random electronic projects, but now i would like to try my luck on effect pedals, and i dont exactly know what effect is the one i should build first, im looking for something not too hard but a challenge that also has an awesome reward, ideas?

What effects are in this song? Answered

In the song "Barely Breathing" by the Hold steady, lead-singer Craig Finn does something interesting with this voice at around 0:19. After watching live versions of the song, I'm pretty sure it's post-production. If it  actually was a series of pedals, how would this be achieved? To me, it sounds like reverb with delay. What do you think? Thanks, Noahh

Arduino Guitar Effects Pedal?

Ive been wanting to do this for some time, but my technical abilities are somewhat lacking, especially in the programming side of things.  Could somebody please join these two projects together for me? and I know this is unpaid work, but you're a kind bunch :-)  P.S. I just realised that this does seem to be a lot of work - two different sets of hardware does complicates things somewhat :-/

Effects of Inductors Coupling?

This is a follow up post from this thread >> (It was about how to fix my Wah-Wah guitar pedal, it turns out the Inductor was not working, so I replaced it) I replaced a broken 500mh INDUCTOR in my guitar pedal with a new one. It works now. However, I am planning on keeping the broken inductor in my wah wah pedal (because it yielded a cool volume pedal sound). I want to rig up the circuit so that I can switch from from the GOOD conductor to the BAD conductor. My questions are: Will there be any major effects from having two inductors coupling? Should I be wary of the 'winding' of the coils? If so, what should I do in order to be consistent with the winding? And out of curiosity, how could I rig this up?  Here is the schematic >> 500mh Inductor = L1 I have 3 terminal DPST switch. This is how I imagine rigging it up: I'm thinking of having wires from the inductor terminals on the PCB wired to a terminal on the SWITCH, then to the INDUCTOR, and then back to the PCB. The same follows for the other (bad) inductor. If this is not clear, please let me know, or feel free to post a better way to rig this up. In summary for this last question How could I rig this circuit to switch between two inductors? Thanks.

is there a pedal that can control the volume of a effect into the mix by bringing the effect(distortion)?

Ok, Im in a group that plays alot of shows and im allways looking for a way to improve my live sound.What im needin to know is if there is a pedal(like a wah or volume) that can sepratly control my distortion with out affectting my original sound.Now i know that most any pedal does have a affect unless its true bypass but i'm wanting to be able to bring my distortion into my sound like a volume pedal but it only needs to control the distortion and not the volume of my amp.I can get a similar effect by rolling back my volme on my guitar and clicking the pedal on while roling my volume back up and it makes the effect of the distorton being 'breathed' into my sound.Anyway i duno if there is a pedal like this or if i would have to build one. i'v heard this idea somewhere before and never heard how or if it has been done so thank you and i hop someone can help me out! thanks!

got an electronics question

Ok, i've got a question for anyone with electronics knowlege... some time back i picked up one of those danelectro fab overdrive pedals. i wasn't expecting much, but for $15 i figured that if i got one usable sound out of it, it would be great and, to be honest, i wasn't disappointed at all... but, i was thinking about buying another and gutting them and putting their innards into a single case to make an overdrive with 2 cascading gain stages. now, the issue i'm having... unless i'm able to wire them up to run off of one 9v, there's no real point to doing this. other than the fun of getting to make some frankenstein effect pedal... which i suppose is reason enough. anyhow, i was wondering if anyone could help me out and tell me if i could run both off of one battery or not. in either case, any additional tips on how to go about wiring them together would be greatly appreciated. thanks...

Is there a difference between a high pass filter with an op amp and a high pass filter without one? Answered

I'm trying to modify a guitar effects pedal of mine to remove some squeaking and decided that a highpass/low pass combo with some potentiometers to modify the highpass and low pass points (since my pedal emits squeaking at different frequencies on different settings) and I was wondering if I should use a high/low pass with an op amp, capacitors, and resistors - or just a simple resistor and capacitor filter. Does anyone know if either configuration is a detriment to sound quality?

Troubleshooting unwanted distortion in a DIY guitar effect pedal? Answered

I built myself one of Moosapotamus' Bass Paraloopers following his design (the updated one, that is) to the letter.  The only modification I did was to remove the low pass filter, since I'm using it for guitar, not bass.  Unfortunately, it has several problems. The one I am most concerned about is some unwanted distortion.  It is fairly mild, but noticeable enough to be a problem when playing clean.  It affects both the dry and wet signal (i.e. it is present when the blend knob is set to both 100% wet and 100% dry).  I do not think the signal from the effects pedal in the loop is overdriving the circuit.  How can I narrow down where/what component this distortion is coming from?  Unfortunately, I do not have an oscilloscope to use for troubleshooting.  Any help is appreciated.

Converting to/from line level signal for guitar effects? Answered

So I've got some effects pedals that don't get along with my Egnater Tweaker's effects loop, namely the HBE Frost Bite Flanger, but my Carbon Copy doesn't do too well either.  I've determined the problem to be the effects loop (which is at line level), and the previously mentioned pedals won't accept line level signals without a significant volume drop and high-end attenuation. So my idea is to convert the line level signal being sent from the effects loop to instrument level, run it though my pedals, and then back up to line level and to the loop's return.  This would do the trick to get it down to the right level, but how do I get it back up to line level?  It's passive so I wouldn't think you could go from -10db to +4db, right? I'm also concerned about introducing noise and tone sucking.  Additionally, the send and return both have a different impedance, would I need to compensate for that? Any ideas on a way to achieve this, or a better method that hasn't occurred to me?  Any help is appreciated.

Guitar Wah Wah Pedal Help!

My VOX Wah Wah pedal (V847) is not working. The bypass is working. However, when I turn ON the wah-wah effect - there is only a clean sound of the guitar and a very THIN sound of the wah-wah, it sounds more like a VOLUME pedal than it does a wah-wah pedal.

Would this simple schematic create an effect similar to that of a Flanger guitar pedal? The diodes prevent the signal from traveling backwards. On the top, the inductor (variable and homemade) slightly delays the signal from the guitar, and it is rejoined with the original signal below it. Would this cause a wobbly effect like a Flanger?

New drums: Kick pedal question. Answered

Greetings! Background: My xmas 'from me to me' present was a Roland TD-9K electronic drum set.  I have a concern with the drum kick.  I think I have it set up properly and it's either a setup problem or a user/technique issue.  The instruction manual says you can adjust (insert list of a bajillion variables) and 'set it up how you like' basically, without explaining how each variable effects the end result. My problem:  The kick pedal is set up as per the instructions and occasionally (every few beats) double-taps.  The hits are extremely close together, and are hardly audible if you're not listening for them, but they do exist in the midi data. (i.e. 1/64th beat later) The hammer is physically bouncing and hitting twice, it's not just spurious noise or an oversensitive pickup.  The brain lcd has a What I can adjust: Technique:  If I move my foot a bit it changes the harmonic frequency of the hammer, and it can solve the problem, but sometimes my foot ends up back where the problem exists The pedal assembly: -Spring return tension -- more tension = ability to hit faster but more effort required, problem exists everywhere from full soft to full firm. -Hammer location - it's centered on the sensor per instructions, and strikes flat and square. I could move the pedal off to one side slightly, or change the effective length of the hammer so it hits higher or lower (would change the periodicity of the system). -Angle of the sensor - per instructions is set straight vertical. -Electronic filtering - I can tell the brain to ignore hits for a period after a given hit to eliminate the spurious hits, but this wrecks my ability to intentionally use techniques where fast double-hits are wanted -'Home' angle of the hammer -- the angular moment with which the hammer moves with each kick.  Setting this too far away tends to make it hit the top of my foot (quite painful), and too short means its hard to make it work. Other Thoughts: I play barefoot, should I have a set of drum shoes?  Would that make a difference? I want to use these also to play rock band thru the midi adapter (people report its fun) -- but the double-hits would seriously impair scoring ability, and I need a way to fix them!

Do I need to invert phase a second time? Answered

I'm building a guitar pedal and I am inverting phase with the initial buffer (TL072). I am then splitting the signal into two parts, dry (no effect) and wet (effect). Each of these will be output as separate channels (left and right) and not mixed back to mono. I plan to send each channel through its own 386 amplifier chip to boost it to a level suitable for headphones. So, what I am wondering, is, should I use the 386 to invert the phase a second time back to normal? Or should I use an op amp at unity gain to do that before I send it to the 386? Or does it not matter if I am not mixing the two signals back to mono?

Guitar Amp Static

Following up on my other thread with soldering, I managed to get my circuit for a distortion pedal all wired up.  I've got the clean end working, and nothing at all on the distorted end, but I'm not concerned about that just yet.  On the clean end, I get a really annoying buzzing sound, like when you turn the amp on with a cable plugged in with no guitar on the other end.  What would be cause of this?  Possibly outside interference since I haven't actually put this into an enclosure yet?  This is the schematic I followed.. and the sound from my amp is similar to this.. No, it's not the amp that's the problem because it works fine without the circuit.
