have we come a long way baby.
in the eyes of the layman its a case with a dime and a few doodads of electronic chip nature.
I think this will drop a few jaws to know that those little pinhead sized thigamabobs are full class D audio amps totaling over 200 watts.
and get this folk ... I got em factory fresh directly from the plant for FREE .. thats right .. honest to goodness freebies.



For those thinking about getting into electronics, its an easy matter to hit up manufacturers for such freebies. they give em away as engineering samples. which translates to a free stockpile to learn with.

of course, you could give me a bushel basket of those things and I wouldn't know what to do with them, other than find a way to shoot 'em or eat 'em???

honestly, its a snap to put most chips to work. they give you typical application schematics in the data sheets.
Op amps and Audio amps are a great place to get started.
but then .. why get started is a question many seem to ask .... hey man we cant let China have ALL the fun ... weve got a reputation to reclaim

Think I will get a bucket of beer and watch this thread. Us non-techies are bound to learn something.

Op amp should be a jfet input type since you have more voltage than current coming out of a guitar ... signal in at C2 and out at C3.
R1 and R4 set gain C1 sets the high frequency roll off C2 and C3 block DC voltages but allow AC to pass which keeps amp and pickups happy ....
D1 and D2 force clipping ...
you now have a start on your own stomp box

Oh this makes sense.

New shooters think reloading is difficult. Non-shooters think hand gun accuracy is non-existent. Now you take some chips, a meaningless drawing and make an amplifier -- yah right.

Now where did I leave my Dillon 450 and S&W 629 snubbie? It is time for load testing.

Problem here is overdrive is something in a 50 some year old Buick and that drawing looks like the floor plan for a house that some high school drafting student created and he isn't going to succeed as a draftsman.

It's all so perfectly clear now.

the schematic was for DG, who is a guitarist like myself.
its not an amp. its a fairly generic stomp box design that a guitarist on a tone quest would spend years experimenting with hence the lack of values.

Guitarist yes,Electronics nope.I don't use stomp boxes for distortion.I let the amp do it's job.To big of an amp and you can't get the sweet spot without alerting the noise police.My favorite amp is an old lafayette that I got from a pawn shop many years ago.Great tone and if I want louder I usually run it through a PA.I have other bigger amps that don't see the use of that little one.
I must add that I use a cry-baby for some things and sometimes leave it slightly depressed for a little extra umph.
I also have to admit that I have a '79 Traynor that is one of the best solidstate amps I've ever heard.25 watts of pure sound.
I have others but those two cover about anything I care to do.Except tick off the neighbors on the next street and I have a 50 watt Crate with a 15in. single speaker for that.
Gotta go make the doughnuts,
DG

since I built my amp ... its quite the obscene machine.
tube fired front end going into solid state finals with more wattage than I have means to measure .. and I can measure to 300W.
my thoughts on the subject is to whip the minions in the front of the house to get the tubes singing then cut the signal down to something that wont vaporize the cat that loves to lay atop the stack for the warmth.
between a mild distortion effects and the tube bias control I built into the preamp I can find a good range of nice sweet spots without getting a ride down town for annihilating the peace. if fact .. I can retain the driven blues tones all the way down to a nice back ground practice volume.

that there is a fine example of a tube amp.
I'd change its front end up a bit in favor of a 12AX7 in a differential arrangement so as to incorporate negative feed back

isn't negative feedback what is used in law enforcement on people with attitude problems?

ya mean attitude like this?
