Tuning a distortion using an oscilloscope and a signal generator

[gigimarga]

hello,

using Visual Analyzer i tried to see what's happening with a sinusoidal signal after passing  through my Dr. Boogey...and the result was:
...all controls are at 100%, excepting the volume which is at 50%...

the question is: is it ok or not???
i must to recognize that i don't know how very well how to "read" the oscilloscope...so some advices would be great!!!

And the result was....... ?
I think you forgot to put something there...

Look at page 26 of in "the Art of Electronics"  Differentiators and also look up high pass filter
The first picture show leading and trailing spikes  You might be able to figure out the time constant by the decay time.
Take careful note then check by ear using the guitar and effect and an amp

What you might try are a few low to high frequency's  that are notes on a guitar/bass.  Set the output to different signal levels all under the max the guitar used with the effect outputs.

start around 80Hz and do maybe 3 different signal levels then move up the scale and test at different levels.  Or just do the notes that you like on the finger board at different levels.  Take notes

If you want to use this with a FF type you will need to make a guitar sim between the card and effect.  A crude sim could be a 10K series resistor look at the duty cycle of the waveform of a FF, thats interesting to look at.

I don't know how much you can tune this way.  I do the math for gain section(s) and high pass section(s) and lowpass section(s) and then change things to add or remove more gain or change turn over frequencies

input R and output drive can matter

Since I usually build my pedals at work, I have to rely on what it looks like until I get home and try them with guitars and amps......what looks good on a scope doesn't always sound good!
