easy way to check your fx loop is to send a signal through the send but without connecting the return. If you get signal through the speakers you got parallel, if you don't you got serial :wink:
I'm in the market of an overdrive pedal to push the input of my DC-5. I can not get it out of my mind to try the Flux Drive...
Tell me your experience of using the Flux Drive with your beloved DC-5.
