so whitestrat, based on what u said, as long as there is a digital effect, the resultant waveform will consists of lotsa "steps" and will not have the "smoothness" of the original waveform, right?
Yes, BUT don't misread this as a "digital effects sound crap" because these days, bit processing has such high resolution that the ear CANNOT tell the difference. If you take a digital effect (say BOSS MT-2) and marry it with the right EQ settings and amp, you'd never know it's digital.
Take this for example. This track was recorded by me thru a PODXTLive and a USB connection straight to a PC. It was recorded in WAV, and then compressed further into MP3. Does this sound digital to you? Is it a bad recording? Are the EFX too digital or crap? You decide.

Most people who claim that digital sounds bad don't know what they're saying actually. 99% of recordings you hear out there are digitally processed. Simply the medium itself is digital (CDs anyone?). But you can hear great tones and sounds from digital recordings. Does this mean the digital sound is bad? No. It basically means that digital technology has the means to recreate hi-fidelity. Listening to John Mayer's recording of his "Try!" concerts is a prime example. It was a great recording, and many of his tones are awesome! But a lot of what we do with effects can and might be represented differently after the recording.
To understand hi-fidelity, you need to know what it means too. Digital has a lot to do with this:
Fidelity basically means faithful reproduction. It's not about how good a sound system can sound, but more about how accurate a system can sound. For example, I've had people tell me that a hi-hat should sound like this rather than like that, and they claim they get it from this CD or that CD played through this system or that system. Problem is, surprisingly, many of these guys haven't even heard a real drumset played live. In a small studio SP room or in a large Live hall, what matters to me is what I hear from the system. If it's a concert, then It better sound like one. If it's a studio cut recording, it better sound like one.
I've heard so-called setups where they try to make a digital studio recording which was recorded track by track sound live by bringing up the mid freq. That's not right. Yes, it can sound good, but to a recording nut, it's wrong. An experienced ear can tell if the recording was done with the full band playing "live" together in the studio, or done track by track. How was that guitar being recorded? 2 mics? 3 mics? I would know from the recording notes of the musician how it's recorded, and how it should sound. Some setups have the wrong reproduction of the recording. I once heard one where the drums were too far in-your-face and the bass way back in the closet, and the left and right channels mixed up. I just shook my head.
Recordings should be presented in as natural a manner as possible. But whether I like the way this effect sounds or not is dependant on my own tastes. But whether it sounds correct or not is not subjective. That's fidelity. So, if your guitar tone to you is like shit, don't blame it on the method of transfer. It's more likely the settings and the way the effects have been built rather than opposed to analog or digital.
But then again:
Gene Simmons (in a Playboy interview) once said: "If you know the difference between the tones of 2 different bass guitars, then I'd say you know too much to really enjoy the music". I think he's right. whahahaha...
