I WISH this unit had more CPU. Not to run multiple amps, just to have a pitch block and reverb block in the same preset would be nice. With pitch, comp, drive, gate, amp, cab, eq, delay, reverb I am pushing 85% CPU. That's not a crazy complex preset and I am NOT a hater. I love Fractal and the FM3. I just wish this thing had more CPU than my AX8. I am now looking at getting an external Reverb pedal to save 30% CPU and I am not thrilled about it.
