Custom/home made overdrive/distortion pedal.

[JDCguitarFan]

Dude, i made this pedal a few weeks ago according to your design, it sounds amazing, great and cheap, cool guitar pedal. Do you have more sucesful designs?

[jaywalker512]

@JDCguitarFan I'm glad you like the pedal. Unfortunately I haven't made any other designs :/

hi dude got some questions before i create my own kind of this:

for power supply: what do u mean by V+ and V+/2?

can you redraw this schematic? i dunno where to put my switch, pots, and that SINE (0 100mV 80). im totally confused now. please make another schematic with clearer symbols. i really want this tone compared to other DIY's but ur schematic is more harder to read for me i guess..

sorry for my english dude. hope u can help me.

[jaywalker512]

@bhorj24 V+ is the main power supply (9v), V+/2 is half of that. The SINE marker is just used for the simulator, but that's where your guitar input goes.

[ARMYStrongHOOAH17]

i have one question, what'd the difference between the fat and skinny settings? is it treble vs. base or something? or high vs. low gain? or what?

[jaywalker512]

@ARMYStrongHOOAH17 The fat position allows more bass through the clipping circuit, giving a "fatter" sound.

[ARMYStrongHOOAH17]

@jaywalker512 ah, okay...thanks.

[lokeycmos]

wow your schematic is pretty simple and sounds great! i built a clone of the wooly mammoth.

[mridularul1]

Hi, I wanted to know what are V1 and V2 in the diagram and what are the arrows at the end of the wires shaped as triangles. Sorry for such a silly question but I am new to schematics thats why.

[jaywalker512]

@mridularul1 V1 and V2 are voltage sources. V2 is where your guitar plugs in, V1 is the power supply. The little triangles pointing down represent ground points.

[mridularul1]

@jaywalker512 and where exactly do i put the pedal in the circuit and the gain and level pots like before the resistance or after the resistance

[DisgaeaDelinquint]

Really nice tone, really thick. I especially like gain at 100 with fat on. That would be perfect for my band! Now all it needs is a little reverb so it doesn't sound so flat. Nice work! 5 stars! :)

[thesaloniandevil]

thx :)

When I find the time for it I'll try and make it :p

btw did you get something to put it in? an enclosure?

and where did u get it ? :p

[jaywalker512]

@thesaloniandevil Nope, it's still in that aluminum tin lol. I know you can get lots of guitar/audio specific parts at smallbearelec (website), but resistors/capacitors/chips are cheaper at mouser.

[thesaloniandevil]

Hi,

I watched the schematic and I've got just some questions

The R5 is the gain pot right? from 1M

and R8 is the level pot but is it 50 or 25k

and is the level pot logaritmic ?

and the source below your input (V2) what is that?

sine(0 100mV 80)

I really would like to make this one when I have the thime :p

[jaywalker512]

@thesaloniandevil Yes, R5 is gain.

R8/R9 form a 50K pot

Not sure if it's log, doesn't really matter to me.

The stuff under V2 are settings in LTspice (circuit simulation program). Don't mind them.

[ARMYStrongHOOAH17]

@thesaloniandevil

volume/level pots are usually, if not always, logarithmic...because supposedly the human ear interprets the intensity of a sound wave differently than a distorted sound wave....or something like that.

dude digging the robe

[DanokaLXN]

I still prefer boss mt 2

[100roberthenry]

ha ha...ive been doing this but with a 386..much more chunky.....check it out breadboard 2 project..

[jmastax]

wow. suprised that a simple LM741 could get the crunch sound.... got any ideas on how to make a decent mini amp running at 18v? like over 1 watt but below 10 watt

[jaywalker512]

@jmastax It'd be fairly easy, just wire in any old (small) monolithic power amp chip after your favorite distortion circuit, and you've got an amp. I've got a TDA8943 power amp chip here (5 watts) that would be easy to use (but it's not very loud at all). Check mouser, that's where I buy all my parts.

[jmastax]

@jaywalker512 well im trying to make a very loud... like... louder than a conversation between 2 people..... but able to go anywhere... their are obviously mini amps built but im trying to do it with no ICs.. unless its an LM741 or LM386.... which i have the LM386 Smokey amp built... but only 1/2 watt of power going through the speaker.

[jaywalker512]

@jmastax If you want to do it with no IC's, you'd want to use a power amp like the TDA2030. However, it'd be a lot more difficult to use since it's not all integrated, and a lot of extra circuitry is required to use it. You could build an amp from 5-15 watts with that chip. Keep in mind tho, that a 5 or 10 watt amp is not very loud. The chip I mentioned previously is about as loud as a normal conversation.

lmaoo yurr fuckin eye

[95tornado]

awesome! what stuff did u use foor this

[jaywalker512]

@95tornado look at the schematic in the description

[Scream7277]

o.o your eye lol but very neat video.

[HolyGK]

Dude, you're eye Freaked me out !!

[jaywalker512]

@HolyGK it was meant to :p

[HolyGK]

@jaywalker512 lol. Nice pedal tho

[poplepo3]

sounds like a danelectro

[jannszki]

Can you make a video of how did you do that project...

sorry for my english, cause im from philippines....

[ScorchinBeats]

My brother's thinking of doing this for his grade 9 science fair. Do you think it'd be too hard?

[jaywalker512]

No, it's not very hard. That'd be a cool project :)

[MiracleKD18]

Awesome!

When i was a child, I dreamed about building an own homemade electric guitar and an amplifier, but gave up long ago....

But this distortion thing.... is just AWESOME!

[DaLoner88]

hahaha You look like a nerd with short hair and glasses :D :P

[jaywalker512]

pff, i am a nerd :p

[reubenbridges]

Xcellent Video

[MrJeekz]

Great job ,man!

[ljvedder]

wow works nicely ^_^ and was probly ALOT!!!!!!!!!! cheaper then buying one from the store

[jaywalker512]

yep, mostly because I had most of the parts I needed. Even if you bought all the parts, you could still build one (one that looks MUCH nicer) for about $20.

[OlloX3]

WTF happen to your hair?!

[jaywalker512]

shaved it off a while ago :p

[AthrunApl]

lol :b
