Hello, I have a HX one set up with the 4 cable method using 2 dirt pedals, delay and wah. The delay and all the modulation effects within the HX one are set to go through the amps loop and the dirt and wah I have set up with the HX one to hit the front of the amp. I use the recommended power supply for the HXone and power the rest of my pedals with a one-spot. What I have noticed is that if I take the HXone out all together, when using my guitar volume control, I can hear very clearly the guitar all the way until I get to 0 through the amp. However, when I hook up the HXone and do the same with my guitar volume control, the sound becomes very unstable as if I have a bad cord and it's gets muffled. I believe I have the HXone set up properly for my dirt and wah, but to confirm I set the Insert Position for delay and modulations to Pre and overdrives to Post within the HXone. Also set the In and Out Level to "Instrument" Bypass Type = DSP Any assistance would be appreciated. Thanks
