The first impression for every user after unboxing that the power button is totally unreliable and cheap quality. Seemingly doesnÂŽt want to power up. Then after 8-10 seconds of continuous pushing it lights up in the end. The same goes for switching it off. Something unguessable, something totally annoying. The other knobs show up a fading green light for the parameter setting, just like a disco device for kids. You never know an exact measure about a given parameter, like volume. Absolutely not recommended for professional usage! The specs describe over 100W output, but in reality at a gig it hardly could come over the acoustic drumÂŽs volume.
JBL usually make quality, but not in this case. My worst purchase ever! Unforunately, the time has gone for sending it back, otherways I would do that immediately.
