i bought at thomann one powerhead, and to my disgust had a treble button led dead.
I returned it and today I received another kemper powerhead with a volumen led dead .i don´t know if it's a manufacturing problem of the last series, but it seems incredible that two new amplifiers have the same problem.
Now I think if over time it will be a robust amplifier, or otherwise is made with poor quality components.
(It is rare that these two amplifiers are passed quality control).
I do not know if anyone in the forum have the same problem, but I'm going to receive the third kemper and it scares me ..... sorry for my english. thanks.
