Hi, I would like to buy a bass guitar interface for Mac/iPad/iPhone and I don't know if I'll go to a iRig HD or a Apogee Jam. They look the same, I only found 3 differences: - iRig HD is a bit cheaper - iRig HD has lightning cable. For apogee jam you have to buy separately - iRig HD has a gain control range of 26 dB. Apogee Jam goes up to 40 dB of gain. Is this gain difference important? Does it make a difference? Thanks!
