Attached it to a mixer with most levels at 12 o'clock and just control volume on mixer, works great, clear echos and reverb.

The reverb is nice, the voice removal does not work and I never expected it to work

The reverb is great

reverb is good for karaoke, echo not so much perhaps more for musical effects.

The reverb is great and I only have to turn up the level to about 3

Reverb and echo sound fake

What's the old joke, with reasonable 'reverb' and/or 'echo' [or both!
