Other than the Rat and the Muff circuit, wich pedals sit right on the line between Distortion and Fuzz?
To translate for everyone else - low gain vs high gain vs even higher gain.I like to distinguish overdrive, distortion, and fuzz on the basis of how long the signal remains above the clipping threshold. Keep in mind that guitar strings lose energy and especially harmonic energy very soon after pick attack. So not only do they tend to fall below clipping threshold very soon, but also lose the harmonic content that we associate with distortion (which is, technically, harmonic content added to the original signal). What we call overdrives increase the initial harmonic content (as well as rearrange which harmonics stick out more or are dialed back), but allow the string to simmer down soon after picking. What we call fuzz is something where the string remains well above whatever the clipping threshold is set at for almost as long as it is vibrating. That can be achieved by moving the threshold lower, raising the signal level up to meet the threshold, or both.
Most OD's create almost 100% odd harmonics.from a tone perspective, OD was light dirt. Beefs up the signal with some nice even order harmonics and gets chuggy.
Most fuzzes create odd + even order harmonics.Fuzz is loose and hairy; more lo fi with more odd order harmonics and can get out of control or splattery at high settings. Distortion is also high gain, but tighter and more focused.
Distortions feature high gain with odd harmonics only, and usually some more aggressive tone filtering.Distortion is also high gain, but tighter and more focused.
Only that it is oversold. Remember that what gets produced/marketed as asymmetrical is based on diodes, and diodes have fixed, rather than relative, forward voltages. So if I push an asymmetrical clipping circuit hard enough, I get a square wave for both half-cycles, with one a slightly higher amplitude than the other.Anything to add re symmetrical / asymmetrical clipping?
Based on what I hear as well as the fact that ODs were designed to imitate tube amp overdrive which is mostly even order harmonics, I'm gonna be skeptical on that one. Like there's gotta be some even in the mix.Most OD's create almost 100% odd harmonics.
Not in disagreement. The way I phrased it above implies in addition to even harmonics. I find fuzzes are a rather wide range of sounds so some may lean more one way than another.Most fuzzes create odd + even order harmonics.
Again, no disagreement there, though I would be hesitant to use the word 'only' and would defer to something more open ended like 'mostly' or 'predominantly,' there's different pedals and they do differ slightly.Distortions feature high gain with odd harmonics only, and usually some more aggressive tone filtering.
They all create all harmonics. Differences lie in the ratios of those harmonics, and how long the harmonics are evident in each picked note's "lifespan". Again, I can't emphasize enough that the string dies out and loses harmonic energy a few milliseconds/cycles after you pick/strum. Guitar strings are NOT oscillators with fixed amplitude and waveshapes. The distortion produced is a byproduct of the input fed to the circuit. If the input signal from the guitar is constant, then the impact of the pedal is more constant.Most OD's create almost 100% odd harmonics.

Believe it or not, if the waveform is clipped identically on the positive & negative swings (e.g., complimentary clipping diodes with no overdriven transistors / op amps in the mix) it's pretty much zero even harmonics.Based on what I hear as well as the fact that ODs were designed to imitate tube amp overdrive which is mostly even order harmonics, I'm gonna be skeptical on that one.

Yup. Agreed, that's what I should have written.Again, no disagreement there, though I would be hesitant to use the word 'only' and would defer to something more open ended like 'mostly' or 'predominantly,' there's different pedals and they do differ slightly.
