I used this with an acoustic, at first with the phone mic- if you play too close or have the track turned up it will clip, not apps fault. Then with headset mic, and ear monitor, works- better sound. Drum tracks bit cheesy but do the job, can turn down after or mute. Is good to have varible beat and signature. No pan, what are you gonna do on your phone anyway produce Robert Fripp! looks just as good as other ones, totally worth 5$ I paid 1$.
