Yeah I remember checking the hi cut function and making sure it wasn’t affecting the signal, that was my first thought too.
According to an old gearslutz thread, a rep at Strymon said that due to the nature of the processing being done by the pedal’s architecture, there may be a delay of roughly 2 samples between the left and right channels when processing stereo signals (this is irrespective of the expected phase effects of the pedal itself). The person who posted about that on GS said that they compensated for this on one channel of the bus with a micro-delay plugin in their DAW and it brought back the clarity and high end of the signal by a major factor.
I emailed Strymon today to find out if maybe there was a possibility for a firmware update that would compensate for this delay internally, but I was told that the Deco wasn’t designed with updateable firmware like some of their other pedals. My comments were passed on to the engineering team, so who knows, maybe I can pray for a hardware revision.
I want an affordable stereo hardware tape simulator with a wow/flutter-like function (in the Deco’s case, “wobble”) and it’s basically the only thing on earth that fulfills that desire. It would be fantastic on the mix bus of a hardware setup, if not for this 2-sample offset.
