I am going to be testing out a used cab I saw on Craigslist soon. I have one just like it, so I already know that I like the sound of this cab (Ampeg SVT 410he). My question is whether I could get a good feel for if there are any problems with it by playing music from an iPad through it as opposed to playing my bass through it. In my current situation, it would be much easier to bring my amp head and my iPad along and just plug in, rather than bringing my bass. I'm wondering if I can get a good trial this way, and if so, does anyone have any suggestions as to what songs might give the cab a good workout? Or, would this just not work so well? What do you all think? Thanks!
