This is an exact hardware replica of the Mutable Instruments Blades module.
Our model uses the original "hard-to-find" opamps, but we do substitute V2164M with AS2164D. All of our products use AS2164D and there should be no measurable change in behavior.
Every module that we sell comes with a 1-year warranty.
If you have any questions about your module, we are here to help.
