These mini amps are great, I have a Roland Micro cube, it has 6 amp models built in plus , chorus, flanger, phaser and tremelo effects and delay and reverb. It's only a 2 watt amp but these small amps really can pack a punch. It can also run on batteries should I decide to go busking ( yeah that's gonna happen ). I also have a digitech multi pedal board with a wah pedal that really allows you to play around with different effects on the Uke. Another sure fire way of putting a smile on my face.
