This is a NUX combo amplifier for bass. It's perfect for practice, acoustic live performances in small venues, and more. It's very convenient. With Bluetooth, it's also ideal for practicing while transcribing music. I'm reluctantly selling it due to decluttering. ■ Output: 50W ■ Speaker: 6.5" 4Ω FRFR Loud Speaker ■ Input Impedance ・INPUT: 1MΩ ・AUX-IN: 100kΩ ■ Power: DC28V center negative, 4A ■ Accessories: AC adapter, AC adapter power cord, dual footswitch ■ Dimensions: 326(H) x 300(W) x 225(D) mm ■ Weight: 7.2 kg *excluding adapter
