I see the Vox DA5 has already been mentioned,
but heres a direct link to their full range of battery powered mobile amps..

plus, a link to the new Line 6 microspider..

I'd expect them to be very reasonable quality and versatile
digital FX equipped working performance tools..

just ignore all the overexcited sales pitch aimed at
teststerone fueled death metal metal kids..

I'm sure any of these amps could be well capable of quieter clean amped sounds
in more mature hands...
