Ok so i`ve had my amp for a few month`s  now and I love it. I also have a Kleinulator for my reverb and delay pedals.
But.....man my carbon copy delay does not work properley in the effects loop (kleinulator). I have to max the send and return on the kleinulator and on the carbon copy the regen and mix to full on...sounds like SHT! heheh and hardly any delay or regen happening.

The delay pedal in front of the amp is ok!...I have good cables and only 10ft long from kleinulator to amp.

My reverb pedal (TC hall of fame) sounds fine in the kleinulator.

Maybe the carbon copy doesnt like being in the effects loop ??

Just wondering if anyone has ever had a similar experience with the HRM and mxr carbon copy in the loop!! thanks
