Bought this amplifier to connect an acoustic guitar and a microphone at the same time. Works like a charm, and sounds really good. I like a real spring reverb a lot with my acoustic guitar. Word of caution: both the EQ settings and the reverb seem to work on both channels (guitar and vocal) simultaneously. And one feature that I find somewhat annoying: both AUX and headphone jacks seem to be old school mono (left channel only on both). The AUX can be easily remedied by setting your phone/laptop audio to mono only. For the headphone, I still did not figure out a simple solution, perhaps an adaptor cable of sorts is needed... Still, a great two channel amp altogether, especially for the price.
