EQ700 : Very high noise floor, practically unusable

This pedal is my first guitar EQ pedal. Once turned on it has a very audible hiss noise. Ironically the hiss can partially be lowered by lowering the highs on the unit itself, but not removed.

It might be ok for players with a very distorted tone that need to shape their signal before the distortion or tame the low end a bit, otherwise, I do not see it as usable at all.

I am sure my unit works is not broken as the hiss sounds like a stacked noise of many noisy mic preamps, and not like any buzz or rattle of bad wiring, or RF interference.

I do not care it is plastic, it feels quite capable of years of studio use for instance.

Pros: It is an eq pedal, the EQ part of it works as expected, mechanically it is ok for the price.

Cons: Practically unusable because of its high noise floor. If you need a noise making machine this thing is great, but as an eq pedal for any cleanish guitar tone it is hopeless.
