Great construction, a little on the heavy side.
After using for some time, no hisses, no high pitch noise, providing what it promises and what you demand. I safely inserted it inside a pb600 pedal board with onboard power supply, and managed to fit it perfectly, despite having to buy an angled power cable for better cable managment, but that cost me no more than 3 euros.
I can safely say it was money well spent and i'm quite happy with this product.
