Great So Far

Ive tried Ampkit, Line 6 POD, Jamup, and AmpliTube (including IAPs), and Tonestack is the best so far. Most amp sims (including PC plugins and outboard hardware) suffer from digital-sounding overtones. Tonestack doesnt seem to display this flaw, and the amps sound thicker and more life-like. I cant say if the sims sound exactly like their true-life counterparts, but I like what I hear.

Ive seen complaints about the user interface, but I like it. Its a personal preference thing, of course.

My only gripe is that it works as an IAA effect and not an instrument. Some apps will only work with IAA instruments (e.g., Beatmaker 2), but the workaround is to use Audiobus. So, this is not a major flaw.

I just bought the Motherload IAP, so Im going to test all the amps out, and possibly update this review if my opinion changes. But Im impressed so far.
