3rd-party software to beta control guitar hardware:. Such software isn't a guitar amp, and isn't a guitar effect box. beta It's hard to find good lists of such software, because the category hasn't officially been created at places such as Harmony Central. Again I suspect this is because the Amplitube company, IK Multimedia, is wholeheartedly committed to actually selling this product, unlike -- I surmise -- Tech21, who seems to be doing a great job of keeping the SansAmp plug-in a secret.
Consider the Tech21/Bomb Factory - SansAmp PSA-1 Plug-in -- surely this is the same product category as Amplitube, and likely sounds about as good, but look at how much more vigorously and effectively Amplitube is being promoted. So packaging, publicity, beta and marketing are very important. Even the good and well-respected THD Hot Plate is unknown to most guitarists, most of whom haven't heard about power attenuators at all. Some well-designed products have beta come and gone, such as the ADA Ampulator and the H&K Crunch Master.
