Thanks, Stringsthings. I had started doing a layout while I was BBQ'ing some chicken. The chicken won out (and was fabulous). I returned and there was a layout waiting for me.
Thanks! I will check out the layout versus the schematic and put it together. I can put my shoes back on and quit strumming my guitar with my feet while I adjust pedals.

and a short ( but exciting ) soundclip:
Just a question. I notice the the "notes" are all quite short. Was it possible to make the notes ring for longer times, but still die out? |

That looks pretty handy. I use my GEO "Down and Dirty" oscillator just to verify if something is functional when I get it done, usually when I am building a batch of pedals for one of my clients. But for stuff I build for myself, I always take the finished circuit for a test drive afterwards by playing my guitar thru it. I guess there are those times when you are tweaking stuff where the "guitar" mode might come in handy, though.
I agree with RG, it seems like the "notes" decay extremely quickly. They are very staccato...

From that sound clip stringsthings posted, it sounds like knocking on a wooden block. Is it any good for testing any pedals other than delay and reverb pedals?

Sounds exactly like the old Boss Dr Rhythm rimshot. I have to build it for that reason.  |

Yeah, something with a more realistic decay (like a guitar string) would be more useful. |

Let's see what we get back.
Sometimes it's tricky to set a ringing oscillator to ring just the right amount. I may have to add a fine tuning knob to get it to ring for up to about half a second. I did notice that mine is very fussy about the ringing time setting.

http://soundclick.com/share?songid=9334230details of soundclip: 1) turning the length control from maximum ( constant tone ) to about 1:00 ... to get the longer notes ... 2) notes into a software fuzz box 3) notes into a software phase shifter 4) notes into a hardware octave divider ( that is older than my cat  ) |

Yeah, this could be quite handy,thank you.
I think I will put it in the same enclosure as my "quick and dirty" test tone generator.

1) turning the length control from maximum ( constant tone ) to about 1:00 ... to get the longer notes ... Ah. That's better! I had something like that in mind, a ringing note, but which dies away in a reasonable time. There is a slight buzz behind the note, even on the first section. Is that an artifact of the recording and playback mechanism, or does the thing actually have a slight buzz in the sound. The reason I ask is that mine didn't do that. I had a pretty much pure tone in all the decaying notes. I could turn up the gain so it would buzz, but mostly it was clean sounding. |

Looks a lot like my May 2010 submission if you ask me... Hey, neat. I hadn't seen that one, but it's another good illustration of how flexible the Twin T can be. |

my unit is sans volume control .... so the buzz is likely a product of taxing the recording software .... |

Ah - OK, that makes sense. In any new design, I'm always aware I could have made a mistake either in the circuit or the drawing.  |

I use them quite often in both personal and professional designs. Simple, cheap and it works well. Something I really want to start playing with is LC tonestacks in guitar amps. Seems like you could get a lot more range by using three pots in conjunction with LC networks. I haven't played with this at all and it's obviously not an original thought, but it seems like it hasn't been explored much (or at least not well documented). Hrmm.. |

Um, well, duzzat come on Lake Placid Blue? Actually you could do a Strat motif with one of your fabulous wooden enclosures and either paint it that color or add a pickguard with the chrome Strat jack too! It would be a Strat in a box!  |

Better add a Muzique Pickup Simulator on the output, if you're gonna go that far.

A simple, hopefully not stupid question..is it possible to modify the circuit so the sound frequency is controlled with only one pot? Thanks!  |
