Hi All, the Samson mini mixer is pretty good in terms of what it is expected to do. I'm using this with my TC helicon Mic Mechanic 2, must say the pre amp is excellent. I'm connecting this mixer - pre amp to my Yamaha Amp. I tested this mixer by playing my Flute and the sound quality is super, there are no hissing / humming sounds and the output is quite clean. I would recommend this those of you who wish to connect a mic, keyboard/guitar for gigs or for jamming purposes, I have used this with my flute as i mentioned on stage and this is pretty awesome !!Regards,Venkat
