I have a reverb setting with a very long decay. I switch it on, play a chord, reverb does it's thing, then I switch it off and reverb is silent. That's all fine, but then minutes later if switch it on again, the reverb seems to take up right where it left off when I switched it off, the chord is still ringing but I haven't played a thing.
I have the unit set to True Bypass.
Is this a glitch or am I doing something wrong?
