Hello, I received the OB-4 a few weeks ago and when I fast forward (ff) the tape (volume knob to the right), I noticed that the tape starts to rewind when turning fully clockwards. It behaves the same, when I use the loop mode.
I reached out to TE, but as I mentioned another bug, they just replied, that the bug was reported to the Development team and will hopefully be fixed in a future update, but I think the problem with the volume Knob is hardware based.
Does your volume knob function as mentioned, or is it (like I think) a fault of my unit?
