I have a couple of top quality acoustic combo's, one mic input + guitar.
'We' are a duo, 2 singers, one female. This 'freeU' 2 mics, has a summed single output jack, separate volumes for each mic.
I'm not into wires any more, so this is perfect for me & my setup. With thoman reliability.
I did try some smaller, more expensive makes, but all had various problems. FreeU has no problems yet and sound quality is great for live gigs.
