Can we start a Demo Video Thread?

[Slade]

Here's the first video of the Classic Germanium Fuzz. It's with an SS amp, I'll upload soon another one with a tube amp.

well done "3hands man" !   




is there a way to DIY a guitar player like that, so we can set up/test our FXs " on the fly"........?

great to see this thread still going.....subscribing to all you guys so I can see your new stuff

my latest creation...not built yet!...but hey..these things take time..

introducing....(trumpets and a drum roll).......'PULSEWAH'

enjoy...

I just got word (from the guitar player) after finding this video posted on youtube that my 250 overdrive pedal DIY clone is being used on this clip! It's the closest to a demo that I can provide right now:

very cool steve...sounds f****g awesome....

he should have showed off  ya pedal though man....nice...

[Steve Mavronis]

This clip is supposed to be part of an instructional video being filmed called "Learn to Burn" so hopefully he will show it but I don't know.

I demo'd the Guild for a friend but after 9:28 it could be a Dr Boogey demo on a crappy tele.

That would be good for video game robot soundtracks.

analog bit crusher breadboard demo. at the end of the video i show the effect with a sine wave through the scope.

Is that basically amplitude modulation? Sounds more or less like a ring modulator, but with more of the original signal and carrier getting through.

That's wild.

[zambo]

its not really a pedal but its a demo of what i been up to latley    http://www.youtube.com/watch?v=sETbe24Bu-4   

[John Lyons]

That sounds great Greg! Nice work.

Hey Thanks! I should have the 10 watt version done tomorow or the next day. I cant wait to hear an el34 in this design. I got a better layout going to so hopefully less buzz and oscillation....fingers crossed....

wouldn't amplitude modulation be a tremolo? no, it's a sample and hold. there are two buffers with a fet switched by a really fast clock in the middle. when it's switched off a small capacitor holds the signal where it was which is held by the buffer. this in effect makes the wave have a ladder and sound like a low bitrate digital signal (atari)

Ok I'm familiar with S/H circuits from synths.  So then the more frequently the sample and hold samples, the greater the number of amplitude levels it is representing, similar to the number of amplitude levels represented by different bit resolutions in digital audio... just that in this case, they are probably not fixed to exact corresponding fixed amplitude depths/voltages, like they would be in digital.

I can see how that would work.

that's right. in fact it seems whenever the circuit is mentioned people jump in to remind that it is not true bit crushing, as you pointed out there's infinite number of amplitude depths and the levels are not fixed. the sound is still right. it's simple and fun but not sure how practical this would be for use without further development removing the noise.

the schematic is here but i had to modify the values to get it working: http://experimentalistsanonymous.com/diy/index.php?dir=Schematics/Fuzz%20and%20Fuzzy%20Noisemakers
