FLY 3 Pack BK : Great sounding mini amp

Something is rattling inside the amp when it is shaken or when doing vibrato on guitar. It is not very loud, but still isn't supposed to be there in the first place.

Em. out sounds lifeless and really not pleasant - goodbye practice in headphones.

Aux cable is not included.

Extension cab won't give you stereo for guitar, only for aux in.

The amp won't sound really good quiet, which beats the purpose of using it in e.g. hotel room for quite practice. If you want it to sound good, you'll have to let your neighbors hear you.

Other than that, great mini amp. The amp's reaction is similar to tube amp - it responds to dynamic playing and cleans up with guitar volume dialed back. Sound is really nice in both clean and OD settings.
