EVA Electronics High Grade Sound Stabilizer III SSPH-HG2 30V Hi-Z Used Thank you for viewing. I am the first owner. While it provides good results on a pedalboard, I personally felt it could alleviate the so-called digital harshness when placed at the front end of a Quad Cortex or Fractal unit. Regarding the power cable, there were instances where the power wouldn't turn on depending on the angle at which the cable was inserted. I confirmed this with the manufacturer through the store where I purchased it, and it's apparently a specification. Rotating the power cable slightly allows it to power on, and once it's on, it operates stably unless the angle of the power cable is changed. I am a non-smoker. I will pack and ship using used cardboard and cushioning materials.
