I know this is an issue that’s been discussed quite a bit, but after trying a few things suggested here and here, my attempts to reduce the noise produced by the Mod Dwarf have not been successful. I am wondering if there are other things I can try to figure out if this is a ground loop issue or if the noise is inherent to the device/12 V power supply block. I might also be doing something wrong in the things that I have already tried, so all suggestions are welcome.
My setup: I currently have just the Dwarf connected to a Headrush amp (no guitar or anything connected to the dwarf), with no software pedals active. I can hear noise that is much higher than any other physical pedals I have tried connecting in a similar configuration. Both the Dwarf and amp are plugged in to the same power strip.
Things I tried:
I tried putting different DI boxes between the Dwarf and my amp and hitting the “ground lift” button on the DI box. The amp also has a “ground lift”. Using ground lift in either case did not reduce the noise. One of the DI boxes simply seemed to lower the overall signal level (I checked this by plugging in a guitar).
I replaced the original power plug with one that did not have a ground, and that did not change the amount of noise.
EDIT: 3. I also did try hitting “Compensate Gnd Loop” under Mod Dwarf settings, but that did not fix the issue.
Here is an example of the noise in Mod Dwarf vs Zoom MS-50G, when no pedal is active in either device.
I have been wanting to try a different 12 V/2 A power block, but might need to order one. Do you guys have additional suggestions for what I could try to lower the noise?
