ReValver 4 is a slept on free guitar amp simulator VST plugin. It may not be as sleek and well known as AmpliTube Custom Shop but we definitely think you should give it a try. It comes with 4 guitar amp, stomp, effects and proprietary ACT (Audio Cloning Technology)™ instrument models. It also comes with custom microphone simulators and ability to change mic positions.
Not only does it come with free guitar amp presets you also have the option to purchase more modules, simulators & upgrades. You will definitely have a lot of fun with the free stuff though. We haven't even finished exploring all of the free presets.
ReValver 4 works as a standalone program and also as an AAX, VST or AU plug-in. That means it works in all DAW programs like FL Studio, Logic Pro X, Ableton Live, Maschine, etc. It also works on PC and MAC which makes it completely universal (unless you make beats on an ipad or something.)
