    Howdy! Just got a Grand Canyon this week and having some issues with the looper. I recorded 3 layers no problem, but after recording my 4th, the first 3 layers would disappear during playback and I’d only be left with the 4th. After undoing the 4th layer, the first 3 would come back and play no problem. I tried unplugging and plugging back in, switching my delay setting, playing with the Loop LVL and Dub LVL knobs to no avail. I’m using the power supply that came with it. Thanks for the help!

    Please excuse my tiny amp.

    Hi see if this helps:

    The DUB LVL knob acts like a feedback control for the looper while overdubbing only. When this knob is at the maximum position, no volume loss will occur to the previously recorded portion of the loop. When the DUB LVL knob is set below maximum,each time the loop cycles during overdub the previous loop volume will be lower than the newly recorded overdub

    From the manual page 25

    Thanks for the quick reply. I tried playing around with the knob but it didn’t fix the problem. In the video you can see I’m not even letting the loop do a full cycle while overdubbing so it shouldn’t have any volume loss.
