From the Tone Report Magazine:
Last, but certainly not least, the Violetta’s tone is warm like the best analog pedals out there. I was convinced the pedal actually was analog, and that Red Witch had somehow figured out a way to fit a bucket brigade chip into the tiny housing. Only after additional research did I learn that the pedal is actually digital. I think the Violetta’s emphasis on the “warmer” frequencies, or its “warm” equalization did the trick. I preferred this warmth to the frequently cold and sterile tone of so many other digital pedals. Tone hounds take note: the Violetta’s a pedal for lovers of analog tone!
