Hello everyone, Has anyone done both ABGU and BGU? I am about finished with BGU and simply cannot belive how much I have improved in this short of time. But I am wondering, since I play mostly acoustic, if ABGU is simply the same information ad BGU - maybe with some additional tips but nothing major - or if it is worth doing ABGU as well. The free sample videos do not appear to have any significantly different theory or lessons as BGU. Any thoughts?
