another thought came to me about two months ago. if you look at craig adertons book that has the tuner in it. it uses an oscilator to vibrate a one meg hz crystal then uses a top octave divider chip to drop the stable pitch down to usable range. hmmmm what couldwe do with this. well i am not about to draw it in pbrush since it took me two days to do it on paper. but here is an idea that i was playing with .
radioshack used to carry all sorts of weird freq. crystals. i mean i found some in musical range. so i thought aobut this. if you can find it. make a medium gain dist pedal. and put a few in the feedback loop, put a few trim pots there and feed it back to the input. so as you play when you hit the right resonant freqeuncy... lets say 1.5khz it will oscialate the crystal and keep that note ringing. if you put a few of them in the loop, maybee put a few momentary switches you can make a few sustain pseudo feedback switches. you can also put them in the negative feedback loop and let them notch out what you don't want.. 60 cycle hum anyone. i have only expiramented with this a little but the results i had were extremely pleasant. maybe some out there can perfect this and make some killer pedals.
I narrowly understand the electronic part of it but if it can be done and tuned to a specific set of parameters[[ by that I mean users set the freq. range, at which part of the neck you want the tone picked up] let say set your gain on dist. down and vol. full up and play above the 12 th fret four some nice singing sustain.... this even sounds like a pseudo pitch shifter or homemade 12 string guitar impersonator :wink: I just had an epiphany well that brain fart is gone. Oh yes once you have the desired tone then double it for the pitch shift effect. ...IF YOU BUILD IT THEY WILL COME. have a nice evening.
they didn't come :(

hey did you ever find that schematic you was talkin about in the above post i emailed you sometime ago just wondered if you found it.
If you found a 50/60Hz crystal you could make something like a hum eliminator, you know, put it at the end of an FX chain or something. But wouldn't that roll off the 50/60Hz (depends on crystal) frequencies of the guitar aswell?

yes.
damn. :D
Audio frequency crystals? I don't think so... they'd be pretty big!! and expensive :!:

rat shack had them at one time
Hahah. You know, I think I saw someone post something similar before, and I think I posted before that you probably confused mhz for khz, or khz for hz. But people here get pissed when I step in and correct them. So I'll just offer that if you can find any crystal that runs at 1kHz or less, show me, and I'll give you a hundred bucks. How about that? :)

hmm, well if i could find them now, i would be building this. but no i asure you i wasn't confused on the mhz khz or hz. quite clearly in fact. but on top of that. could always use the top octave divider chip like i said before. the whole reason i pulled this thread out was because idle faction said he had done somehting along this lines and i was wondering if he found the schematic for it as i towuld be interesing to research further. no one minds when you correct them there drew, sometimes we all just jump on the wrong section of the thread that we are trying to prove. myself included.
'Member, a crystal's different from a "crystal oscillator"... :)
The top octave idea is pretty useful in a lot of applications though, ansil... something you might be interested in is this multi-suboctave generator:
http://www.cgs.synth.net/modules/subosc.html
It takes two inputs, and outputs several suboctaves from each input, as well as the squared-up inputs digitally multiplied with XORs... so you get a ring mod out of it too. I use mine when mixing but it would work well for guitar, even though you might need a preamp tacked onto the front end.
Where do crystals fit into this? Well, if you wanted to play with a divided-down crystal oscillator, you could feed it into one input, as the carrier for the pseudo-ring-mod, and get sub-octaves/other divided-down intervals out of your guitar signal as well. A little off-topic, but interesting nonetheless! :)

dude i havent' typed like that since i did opium like 15 years ago and that wasnt' on purpose
Apparantly 'Alice in Wonderland' was written by someone on an opium trip. It explains the hyperactive rabbit :D

Lewis Carroll may have had experience with a number of compounds, or at least he had knowledge of them. You have a hookah-smoking caterpillar sitting on a big mushroom, and you have mushrooms and drinks creating perceptual distortion when consumed. Above all, he pokes at Victorian society and it's characteristics more than anything else. I think that is where the high-speed rabbit is from.
Sex, drugs, and Rock&Roll...... Whatever happened to wine, women, and song?
Hmmm. :mrgreen: I think victorian people look kinda cute :mrgreen:
:lol: I agree. If you need another opinion, just ask Alice.......... when she's ten feet tall. ;)
