Does anyone know what this sounds like?


Thanks!

My friend built an amplifier; one channel-distortion only, 100w, solid state.  The preamp was loosely based on a hendrix fuzz.  2 silicon transistors, yadda yadda; that sort of thing, but tweeked a lot.  We hooked it up to his oscilloscope and it was a perfect square wave, which was exactly what he was going for.

It sounded horrible.

To answer more specifically; it sounded like the most horrible fuzz ever.  Sure was loud though.

Download audacity its free, its a small 4mb more less multitrack program, there you can generate it with the frequency you want also triangle waves too.

from "Tim Escobedo's Circuit Snippets...."Super Simple Squarewave Shaper"...

THE SCHEMATIC IS HERE
HERE'S THE SOUND SAMPLE

Marcos - Munky

Yeah, Arn is asking about Tim's circuit. I built it a long time ago on breadboard, if I remember correct it have a kind of synth sound.

Thanks!  Just needed to hear it. Not a sound I am looking for tho!


Peace!

Like anything that just amps the signal hugely & squares it off, it is OK for a single note.... provided the note is reasonably clean, otherwise it is going to false trigger. There is a conflict in squarers between wanting some hysteresis to avoid switching on noise, and yet beign able to still operate as the input signal fades away.
Once you try compensating for this kind of thing, it's not 'simple' any more.

a slightly boosted signal sent into a schmitt-trigger...it cant do anything but squarewave..thats what schitt-triggers do..very "synth-like"...suggested this in the lounge a few years ago...even gave the idea a name.. Mr-Schmitt...

I'm sure I've written it down before, but the Simple Square Wave Shaper is one of my all time favorites. It has sustain for a month, and synthy/fuzzy thing going on that I like a lot. Mine sounds quite a bit like the sample. It's a tone you have to like though, because it's output pretty much substitutes for any natural guitar tone. I don't like it for everything, but I use it quite a bit.

Look at "PWM" on that same circuit snippets page. Yup, that's a Schmitt trigger.

What does it sounds like? Is there any audio examples of it, like what it sounds like if we put all the volume and fuzz to maximum?

If there's no example, what are the closest examples of modern fuzz pedals that sound similar to your friend's fuzz pedal?

Oh my bad. I wanna know what perfect square waves actually sound like.

There's probably a gazillion synth demos out there on YouTube.  Pick one (an analogue monosynth would be a good place to start) and listen for the bit where they say, "and this is the square wave".  Here's one comparing sine vs. square:
