I'm very frustrated at the moment.
I have the Dream Rig with the JTV59, HD500 and DT25 and I love it but want to use some Overdrive Pedals I have with it and am having a big problem with a high pitched whine which sounds like a cross between a hairdryer and the sounds you hear in your ears when you get an audio test done on your hearing. This happens at varying volume depending on how much level and gain you use on the OD pedals and when they're switched on.
I want to use the Super Signa Drive, Joyo Ultimate Drive and Joyo Sweet Baby.
So far I've tried using the FX Loop and running the pedals before the POD HD via normal cable instead of the VDI.
I've tried different cables and patches, made sure there's no interaction with power cables and tried each pedal either singlely or in different combos. I've noticed that when I turn the drive knob on the DT25 right off, the noise disappears but then you get low volume and no crunch. I've tried all the different voicings on the DT25 and it certainly changes the noise but is still there at different volumes. I have also tried changing the Line/Stomp switch and just about every other setting I can think of.
I really don't think its the OD pedals as they work fine without the pod and just direct to the DT25 although the volume is way down.
There is no annoying noise or problems when it is just the Dream Rig without the extra pedals even when on heavier distorted sounds.
My next step was to perhaps try and change impedance input levels. I also have replacement valves for the DT25 and will see if that makes a difference. I'm not sure if I've tried it but I'll also have the OD Pedals in the FX Loop or in front of the pod but this time go from the POD to Amp via 1/4 mono instead of L6 Link.
Does anyone have any other suggestions?
