Conversion is 24 bit. Sample rate varies. Be aware that these are guitar pedals, so the overall sound is more important than the digital stuff.

Thank you for your answer. But as far as I am using these stompboxes with saxophones the conversion process has a great importance in order to respect the original sound especially with harmonizer, reverbs, delays…

Is it possible to have an idea of the sample rate with some classic effects as Hall reverb, Diatonic harmonizer, Vintage and Digital delay, looper… ?

Thank you
