The AMP-TWD-5U is a fun and handy ukulele amplifier from Kala. The amp was inspired by the legendary vintage tweed amps. The amp is portable which means it can be used everywhere. It also only weights two kilos and can be used without an adapter. The amp can be used with just two 9 volt batteries. However, the amp can also still be used with an adapter. As such, it’s the ideal amp to be used outside, although you can also connect your headphones to the amp so you can play in peace. You can also connect your phone to the amp which means you can play along with your favourite music.
