I recently purchased a Helix demo unit from Sweetwater. The unit came looking new and with all updates performed.
My issue is:
No matter how I hook this up, 4 cable method (my M13 works flawlessly using this), straight into the front of the amp etc, there is an unprocessed dry guitar signal on every effect. I've edited the blocks to vary wet/dry, level etc. yet nothing removes this underlying dry signal.
Is there any help, advice, fixes for such a thing or is it possible I have a defective unit?
I've factory reset this and still have this issue.
Any help is greatly appreciated as I still have a 3 week window to return.
Thanks!
Frank
