Hi all! If I have a looper running on the FX loop with the master volumen at 10 or with the master in any setting, and you turn down OD channels volume you can't listen the looper. Maybe it's a normal funtion but I think the TSL60 looper it's so strange. Some TSL60 user here? Also the return level signal from fx it's really weak on It, low volume. Thanks so much!
