Strange that you still got the hiss even having the Custom Shop open (I'm using a mac, so not sure if that makes a difference). I was ok with the UI in general, probably because I found TH3 so frustrating on my 13' Mac Air screen. But the one thing I don't understand is why Amplitube has 8 preset routing options, rather than just letting the user pick their own routing schemes. It took me a while to figure out how the flow of these different routing schemes impacted mono and stereo output. I plunked down the $500 for Amplitube Max yesterday by purchasing through the Custom Shop app. Most (but not all - like 95%) of the amp, cab, mic, pedal, and outboard models are available in Max (a few ). You can buy individually through the Custom Shop app as well, but I typically just buy bundles anyhow. One thing that really irked me was many of the Boogie presets rely use a Boogie slanted cab, and that cab did was not included in the Max bundle, so many of the patches throw a warning dialog box. Many of the other included cabs work great as a replacement, but a huge selling point Amplitube markets with Max is that you're getting all the Boogie amps, so I don't understand why they wouldn't throw in the cab that most of the Boogie presets include. Annoying!!! Here's everything that's not included in Max, in case you're wondering: 2 Fulltone rack modules Ampeg amps SVT-VR, V-48, Heritage B-15N and corresponding cabs 7 of 21 Fender Amps and their corresponding cabs (mostly the '57 models) Mesa 4x12 Reco Slant cab and 2x12 Transatlantic cab There's so much more in in this bundle than I'll ever use... it was the variety of rack and pedal FX that I wanted more than a hundred vintage amp and cab models I'll never use. So the few excluded models are not a big deal for me personally, it's more of an annoyance that you buy their top end bundle and still don't get everything included. It's like they want to squeeze a few extra bucks out of the consumer via those Boogie cabs and the annoying dialog boxes when you pull up a dependent preset.
