hey dino,

just a heads-up, i'm starting on the talkalizer today i think..i've got a spare crybaby shell dieing to get stuffed.



will report back as it comes together!

Be gentle bro.... please.

be afraid...VERY AFRAID!! lol

i got sidetracked.

some kid stole my lunch money.

the penguins were beating me again.

My advise to you bro; Steal the lunch money from the penguins, and beat that kid to a pulp. You should be good to go then.

I put together the Vocalizer from Dino's vero layout and it sounded pretty cool. Thanks!
Though I had found it distorted on the cleanest setting and found that lowering the 330K feedback resistor on
the clean opamp preamp section to 100K worked quite well to keep it from overdriving the filters.
Perhaps the issue with the fuzz not cleaning up completely with the 10K pot was actually this.
It now seems to be distortion-free on the clean side using the stock 10k pot.

[cortezthekiller]

I also used a 10K volume pot ( as opposed to the suggested 1K) to make up for some of the volume lost lowering the clean gain.
There is also now a wider variation in volume between the clean and fuzz levels, so the volume pot is key with the change.

thanks for the info!!

i still have a spare pot for this circuit, and tho the original is long gone have been toying with making another one.

i ALWAYS had issues with mine, never happy with the distortion.. perhaps this will make a diff.

i've noticed on many circuits schematics it seems like values are off from what really works...
makes me wonder if thats cuz they didn't want guys like us figuring it out

or maybe they were mistakes.

while revisiting RG's Geofex.com site recently for the technology of the fuzzface article, i noticed he refers to the output cap on the page as both .1 and .01... and i'm like... hmmm... which is it? (i like a .4 there... or was it .04???   )

i mean, it's easy to be off by a factor of 10 or a hundred or even a thousand. all ya gotta do is mistake one color for another and blammo, suddenly everything is weird.

in production ya figure out what works and stick with it... and maybe don't update the schematic. beats me.

but nice work cortez!!!

cani trouble ya for some clips?

Hey Jimi I made a quick recording with a loop of guitar playing since I don't have it boxed yet:

I went through most of the settings, ( I also added the 10K "range" control).

[pinkjimiphoton]

sounds killer!! the resonance when ya kick the fuzz in sounds almost like tuvan thoat singing kinda stuff... well done bro!

[digi2t]

The Vocalizer wasn't that great insofar as resonance was concerned because the front end was pretty weak. On the other hand, the Talking Pedal front end was superb, but the back end was a PITA due to the unobtainium dual pot setup. That's why I developed the Talk-a-lizer. Best of both worlds. Also cleans up WAY better with the guitar volume. You might want to check that one out.

[cortezthekiller]

Ya I know what you mean. I have an old talking pedal and it certainly has a smoother fuzz that works better with the vocal qualities of the filter.
If I build another vocalizer I may do as you suggest and use the talking pedal front-end. For now I wanted to see how the original one sounded and worked first. Your "talkalizer" did sound pretty good and was a neat way to get the best of both.

I also have been trying different value pots for the filter sweep (10kA, 50KB, 50KA), and they all give a different range and movement to the vowel sounds. The 22K pot I have only rotates 90 degrees from end to end so the sweep is quite abrupt and jumpy.

The 22K pot I have only rotates 90 degrees from end to end so the sweep is quite abrupt and jumpy.

That's where the germanium transistor comes into play as well. It provides a softer knee when sweeping through the range. Try a silicon PNP in it's place, and you'll hear the difference right away. You think it's "jumpy" now...  Try different Ge's in there, the different gains/leakages will affect the vocal sweep.

I found that the 22K Omeg dual linear (270 degree) works fine. I did have to shave the rubber bumpers, and tweak the pot position though to get a nice sweep. Personally, I prefer running it clean, with some other dirt in front.

You could try tweaking the 2K2 at the 3080, or the 3K resistor on the Ge's emitter too. It might help with the filter transition. Never tried it myself, so I'm spitballing here.
