RAS .. but the interface is not as attractive as soft as AmpliTube, guitar rig and consort ... and probably gain a little "facelift" .. but it is not the most important.
a little long to change presets and some "bug" in the management of minor soft but nothing too serious ... and it will probably fix soon.
modeling bcp ago today ... Head Case makes a clear difference in the simulation of cab and it offers up above the rest, both in terms of the flexibility it offers configuration (choice of cabinet , hps, micro + investment, but also floor, wall and room size) than the quality thereof. This is the (or one of) the best (s) simulation of current cab without a doubt.
If in addition you have the IR in Redwirez ... there is a dedicated section (the iFace the developer actually) which allows you to use very easily .. the result is excellent!
heads and effects are limited in number compared to the competition, but allow you to tackle any style and classic if you're in your choice, it will be good enough!
for the rest there bcp good ideas (each part can be used independently of the other pedal construction kit and head etc), and the app is a price quite correct for what it offers ($ 60 CAD / 45 EUR ). It is therefore a very good choice if you want a good sound foremost, flexibility without taking the head of hours, and something quite plug & play .. without having to pay 200 euros left to sacrifice just aesthetics.
