I've been hearing a static sound for the past several weeks across multiple presets. It's been bugging me enough that I spent some time trying to track down the source, and I think I've definitely got it narrowed down to the FM9. With a very simple patch, and no other pedals I'm still getting the sound both through the SPDIF and USB interfaces.
It sounds like a second layer of digital noise over the original signal. Almost like a ring mod. The static doesn't change in volume if I change the guitar volume. It also only seems to affect some notes, but it's very repeatable. It's most noticeable playing a B on the G and D strings. I hear it even if the chain is just In 1 -> Tube Pre -> Cab -> Out 1. The type or turning off the noise gate has no effect. I've attached a recording. I'm moving through some notes so you can hear it only affects certain notes, and it's completely repeatable.
