Lightbulb A String of Digital Pedals = ?

Hey good people. I have been checking out a lot of my friend's friends' rigs and I would often come across pedalboards with a mix of both analogue and digital effects. I understand that with analogue pedals you usually retain a lot of the character of the original signal compared to most digital pedals which, in turn, convert the signal into data before doing anything to it.

Going back to the pedalboards I've seen so far, there would usually be multieffects with other pedals hooked either to the front, the loop, or the back end of it. Aside from that, there would also be other analog pedals in other parts of the chain. I was just wondering how people deal with the apparent signal loss due to such a setup? I mean, I've tried experimenting with a test digital recording converted and reconverted in a similar manner by use of analog and digital means and frankly, results weren't too pretty.

use pedals with true bypass? Or get a GCX audio switcher/something similiar. Also use good cables (24k connections).

Check out this article http://proguitarshop.com/andyscorner/

The part that got me was:
Quote:
But the myth of true bypass gets busted hard when you talk about true bypass pedals and signal integrity over the length of stage sized cables. Without getting into capacitance and low/high impedance explanations, your signal goes through changes which will affect your tone and thatís one reason buffers were placed in pedals to begin with.

So according to this, the entire true bypass is a Myth.

Re: A String of Digital Pedals = ?

I was asking this not because of true bypass in pedals. I was asking whether or not the guitar's natural sound was preserved well through such a string of digital effect pedals, because the way I perceive it, not only does the signal have to pass through a lot of wire before hitting the front end of the amp, it also has to be A/D/A converted a number of times too, assuming that a player uses at least two of the digital effects at the same time (e.g. Ibanez TS808 + Boss ME70 + Line 6 FM4 + Line 6 DL4 + Boss RV5). Now wouldn't the resulting signal be altered to the point where it may have undesirable artifacts of some sort due to the numerous stages of processing it undergoes?

Re: A String of Digital Pedals = ?

This is a really good point, if you keep the signal levels within the limits required by the digital pedals (avoid clipping), then the quality should be as good as if the pedals were good analogue ones. The A/D/A conversion could not introduce any artifacts you can hear.
I've always thought digital pedals, of any sort from any manufacturer should have a common digital bus on them (like the idea of midi, not actual midi as that won't do, but like the idea of midi, a common digital standard) so you go into the A/D converter on the first pedal, then digital through the rest and then the D/A on the last pedal.
As for true bypass, people will never agree on this...

Re: A String of Digital Pedals = ?

It's all a matter of one's points of reference. I for one am not really leaning toward a particular side in this pedal bypass debate. As long as the signal stays clear and unaffected, I'll be happy.

Re: A String of Digital Pedals = ?

Regardless if you buy into the "true bypass", GCX audio switchers and similar i'd still recommend for nearly any rig
