I recently bought an iPad and interface strictly for home recording. I want to use my guitar and pedals for my main affect. The only software I want to use is amp simulation (I really need about 4: ultra clean, Fender, and two Marshall-esque versatile dirty amps to be pushed by pedals) and recording so I can home record quietly. Tone matters and JamUp seems highly regarded. My question is so very little is explained about JamUp on its' site. It says it has a huge number of amps but I cannot find which models listed anywhere. Packages seem configured so you cannot buy just amps. Will someone explain how to find out how to buy what I need?
