Daisychain: HX Stomp + Shure GLXD16 with Isolator adapter

Recommended Posts



I tried to power my HX Stomp and Shure GLXD16 (Guitar wireless system/Tuner pedal) via Daisychain with a Truetone 1 Spot power supply. (With an 2,1mm to 2,5mm barrel adapter).
As assumed there was ground loop noise.
So now I like to isolate the side of the daisychain that feeds the GLXD16 with a Joyo noise blocker (Isolator adapter).

1 Spot provides 1700mA/9V
GLXD16 needs 250mA/9V 》Joyos workingcurrent 800mA
1450mA/9V left for HX Stomp

Before I order the 1 Spot (I borrowed one for testing) and Joyo I like to know your thoughts about this.
Perhaps someone has already tried something like that.

Thank you

I tried powering both devices with the 1 spot. I put the Joyo ZPG before the Shure GLXD.

No ripple noise / ground loop hum anymore. PERFECT :-)
