Peavey has an interesting piece of software called ReValver 4. It’s an exceedingly clever name, but its purpose is more clever. You can sample a guitar sound and ReValver 4 will turn that sample into a model for you. There are a lot of glorious guitar sounds out there, and ReValver brings them to you without a lot of muss or fuss. I haven’t personally tested it, but I’ve spent more than my fair share of time chasing down rigs used by particular guitarists over the years. ReValver’s approach is an intriguing idea—it runs on Mac and Windows. It’s a free download, with additional models available for purchase.
