Je ne sais pas si ça répond à ta question mais j'ai trouvé ça sur la DA-2:
Citation:
What's the twist? Well... The Boss DA-2 is an Adaptive Distortion. It's a pretty cool concept, the processor inside the pedal constantly analyses the input signal, and depending on a number of variables, it tweaks internal parameters to produce a constantly adapting distortion sound.
These parameters include compression, multiband EQ, and gain. For example, if you are kicking into a solo, the pedal will analyse the frequencies of the input signal, and see that you are using a lot of frequencies in the higher mid-range.
It will then eliminate, or reduce, a number of lower frequencies from the output signal altogether, so you don't get any low-end feedback whilst you're on the higher strings.
On top of this, it will also boost the mid frequencies, so that you're solo will cut through the mix when you are playing live with your band.
Pretty cool eh? We thought so. There is also an advantage to having a compressor within the Boss DA-2.
When playing at lower volumes (and therefore putting a lower input signal into the pedal), you get a slight boost in volume from the compressor, but the tone still sounds organic because you still get the effect of not clipping the signal so much and therefore having less gain.
The harder you play, the more distortion you get, because a hotter input signal is leading to more gain.
But the compressor keeps your distortion tight on the low-end, so that when you play chuggy power chords, you can still hear the timbre of the plectrum on the strings, and you get a tight punchy tone without the low-end fuzz sometimes produced at high gain levels.
Sinon ces 3 pédales sont assez spéciales, jusque-là boss faisait des pédales relativement simples à appréhender, il suffisait de lire le nom de la pédale pour comprendre ce que ça fait (chorus flanger od, etc).
Pour le coup on a des pédales vraiment barrées, la TE-2 en guise de Delay++ (avec effet Fairy Dust, swirl et compagnie), la MO-2 en guise de Chorus++ (overtone, detune, etc). Je serais vraiment curieux de tester ces 2 là en particulier
