I'm selling this because I no longer need it, having bought it to connect a guitar or keyboard. It hasn't been used much. It runs on batteries, so it's great for practicing outdoors, or as a backup for students when they can't use the school's amp. It's a very versatile amp. It also has spatial effects and a tuner, so I highly recommend it. An AC adapter is also included, so you can use it with a power outlet without using batteries. I'll offer a slightly lower price if you can pick it up in person. No returns or exchanges. Thank you!
