Best. Filter. EVER.
At least out of those I've used. I always love filters but getting them to work in a mix can be tough for me. Not so with the Xerograph Deluxe. Shit just WORKS in heavy music. It reminds me of everything I loved about the Moogerfooger filter, but much easier to dial in and far nicer to coexist with other units on a pedalboard.
Honestly it's all and with this wee sumbitch.
