The Risa Stick is loud enough to hear what you are playing. If you are in a hotel room it is not loud enough to be heard in the next room, but you spouse can hear it in a quiet room. But it won't disturb them if they are asleep. It's not as loud as a Godin Multiuke unplugged.
Another good option is an EleUke Bluetooth. You can't hear much unplugged, but it has Bluetooth to play through your phone, tablet, laptop or you can link a pair of Bluetooth earphones and listen to your playing.
