IK Mutimedia iRig HD2, "feedback free" apparatus for electric guitar on digital media recording.

I was using the first gen 19USD iRig, and there was too much feedback that I couldn't play or increase gain, or had too put a lot of noise suppressor to play just right. Now, HD2 has gone smooth and no feed backing hardware that saved my life. This video is the proof: with ipad air on a regular Philips stereo as an output speaker, using Jam Up Pro software, I turned on gain to the fullest, turn on compressor to very high setting, and noise suppressor in its lowest setting is making the room dead silent. Without noise killer, the background hiss is no more than your usual stack amp noise, that is the regular, expected noise means no harm. HD2 is fine!
As you have noticed, iRig HD2 led is blue in natural state, but beats bright blue "normal volume input from guitar", yellow "strong input cracking sound", orange "gained input signal, or red "extreme signal input" as you hit the strings, but not in this video, because I had to prerecord and "sample" the riffs to make the video... result wouldn't change even if I playd live, because I have used the same pedals setting on Jam Up Pro XT to record.
The video and sound recording is made with Samsung ON7 phone, with its own mic, open aired, uploaded raw !
