Hi! I bought a new Kemper Stage. The bottom button on the left does not work, and does not emit a characteristic “click” like all other buttons.
There is no time to bother with a guarantee, I have concerts. Therefore, I wanted to ask. Who knows what characteristics of this button, I will find one in my city (Moscow) and give it to my master, who will quickly fix it.
What kind of button is needed, its characteristics, to replace the broken?
