Unveiling of the pedal

[SparkyCal]

Finally...thanks to all your help, i have finalized my pedal build and have recorded a sample of wjhat the pedal sounds like.

I have the volume down, but the gain up, and the tone control at around 1 o clock.

It's not perfect, but it's good for my first attempt. The nexyt time I build this, i will include suggestions from AudioGuru, and see how that sounds. In the interim, have a listen:

Sounds good. Well done

nice guitar work. Best wishes for your future sound projects.

Thanks guys. As for the guitar work, it was actually pretty s;loppy as I was concentrating on not having the pedal fall off of a seat i had placed it on.

I am now rebuilding the pedal, using AudioGuru's amended design.

Didn't I ALSO hear some additional reverb ?

 

[ratstar]

Yep I hear it 2. Is it a room recording?

 

[SparkyCal]

The reverb is a function of the Fender Hotrod Deluxe amp I put it through. My amp normally has a touch of reverb dialed in and I did not bother to turn it down when I recorded. Has nothing to do with the pedal.

I am glad that it produces the awful distortion that you like and want.
At the beginning of the recording before you play and at the end after you play I hear a 180Hz background noise. Your electricity is probably 50Hz, not 90Hz. Maybe your electricity is 60Hz then the interference is a squarewave which would produce the 3rd harmonic at 180Hz, and the pedal circuit cannot pass the 60Hz.

Adding the protection resistor to the tone control will not affect the way it sounds.

Your guitar playing is excellent..

 

[SparkyCal]

Thanks AudioGuru. Let's see what it sounds like when I build the version you posted. I'll post a sample once I get that done.

By the way. As I mentioned, this is just a project. I won't be using this on stage. However, what would you say is a good sounding distortion? Is there a schematic that you believe will produce a better distorted sound? If so, I'm willing to try it.

 

[Audioguru]

Distortion adds many high frequency harmonics that sound harsh to people with good hearing but the distortion harmonics are reduced if people have poor hearing from old age or caused by playing loudly in a band or shooting guns in a war.

Or alternately, if the audio guy plays with the EQ to reduce some of the harmonics that aren't "nice"

 

[SparkyCal]

I’m not sure if you just prefer a clean sound over distortion, or if you just don’t like the sound if this particular schematic. That’s why I asked whether you had a better option in mind.

 

[Audioguru]

I prefer the sound of an acoustic guitar. Electric guitars are rarely played clean because in "the good old days" amplifiers had tons of distortion and today they are trying to match that awful harsh sound.

I think the circuit you have with diodes in the opamp feedback produces "soft" clipping and the other circuit you showed with the diodes at the output of the opamp produces "hard" clipping. Maybe you should switch between them to select which one you like.
