Creative Amplifier Project (CAP) is a creative plug-in that simulates a simple guitar amplifier with a compressor and a distortion (but it isn't an amplifier emulation).
The size of the cabinet (and the size of the speaker) can be changed smoothly in real-time and via automation allowing interesting effects to be obtained.
If anyone has a copy or knows where to get it I would appreciate it.
wow thanks! I tried following the links to those same downloads on tehir site from other palces, but for some reason they wored via archive.org - never thought of that.
