Je n'ai pas de focusrite et je n'ai jamais utilisé Ableton mais sur ta 2i2 tu dois pouvoir couper le monitoring direct (qui te fait entendre le son brut de ta guitare).
“The type of cap is not as important as the value of the cap, for guitar. In an Amp, your cap type is much more important, as the signal is being passed through the cap all the time. In a guitar, you’re not hearing the cap itself, you’re hearing what the cap is impeding”. Lindy Fralin
