Erica Synths Zen Delay

Be aware that the Zen Delay has an annoying high frequency tone when both delay and filter are active. Since the filter and drive signal path is analogue you will have some analogue signal noise. That's totally fine. It's even the reason I want an analogue circuit. It's the character of this device. But this tone is different. It's a high frequency tone that is audible while playing music. It's especially audible when using that BP filter 2/3 open. For me this is unusable.

I had high hopes for this unit, but it's not a great delay or filter, and it's far too expensive for what it is.
