Amplifier modeling has reached new heights of realism, and it’s to the point where even die-hard purists with big amp collections now show up to a session or a gig with just a modeling pedal. That said, one of the big problems with amp emulators has always been how difficult it is to get acoustic feedback. Let’s face it, you have to move some air first to get that sound that we all love so much. Until now, that is. Softube’s Acoustic Feedback plugin now allows you to get as much or as little real sounding acoustic feedback while staying exclusively in-the-box.
Acoustic Feedback has actually been around for while but I’m only getting hip to it now (thanks, Oz Amaro!). The plug is an offshoot of the White Marshall amp simulation from Softube’s Vintage Amp Room, although the one supplied is a stripped down version (that’s all you really need for feedback). It’s very cool in that it’s fully responsive to vibratos, bends, slides, and tremolos so it tracks your playing well. The user interface is simple: there’s a Mix control, a Feedback amount control that goes from subtle to natural to wild, and a Tolerance control that tracks your playing.
Best of all, you can assign a MIDI foot controller to the Feedback control to manually adjust the amount so it responds just like you were in front of a cranked Marshall!
Acoustic Feedback is available for VST, VST3, Audio Units, AAX Native and AAX DSP formats, and is just $49 with a 20 day trial period. You can find out more info here.
For those of you who gig with a modeling pedal and don’t want to drag your computer with you, Fender made a version of this called that Runaway pedal that combined the Softube Acoustic Feedback algorithm with a built-in foot pedal. Unfortunately, it’s no longer available, but you might be able to find one used.
