Looks like other amps, yes, but other amps haven´t memory readers built in, this is awesome because you dont ned to connect any AUX IN device, forget the iPod or your cellphone, I will record inside the TF card the Radio Chatter 501st files (CT and others), then I will choose the file with the remote control and put in LOOP mode (before you needed to record the same file once and again to build an hour or less duration file and connect that device in the AUX IN), simple press the loop, PLAY and the background is ready.
The mic is cardiod and will avoid amplify the sounds coming from down, avoiding the feedbacks and the Reverberation function will create the echo sound added to your voice.
I am planning the demo video and I will upload to utube and the link here.
The best way to look the workable apps is in a video.
Thanks for looking, soon more info.
