Research, what a blast.

Hey there, Hi there, Ho there,
It's your friendly posting host again. I've been very busy as of late, schoolwork and what-not. Let's see ...hmmmm.
New features in AmpliTube® Fender include the addition of three new user-requested “stompbox” effects and a rack unit:

A classic stompbox Fender compressor, based on the compressor in the Fender Cyber-Twin® SE, provides a more consistent and higher input signal at the amp input stage, with four available “levels” of compression/gain.

A new wah pedal, based on the wah effect in the Fender Cyber Twin SE, offers two “wah” voicing options—the “Cryin’” and “McCoy”—and provides detailed control of the amount, effect frequency range and output level of the effect.

A new Fender tremolo pedal provides that world-famous Fender amp tremolo effect in a convenient stompbox, giving players more front-end flexibility for tone shaping, plus adding the magic of the Fender tremolo to any non-tremolo amp model.

A new rack unit: The Fender ’63 Reverb Tank allows for post-amplification reverb effects. The reverb unit is based on the famous ’63 spring reverb tank and provides the rich, lush reverb effects Fender is famous for.
