Waves has come up with an appealing promotion for its GTR Solo package: you can now download and use it for free for a whole year.
To help you complete your tone, GTR Solo also features 13 stomp boxes. These cover distortion, modulation and ambient effects.
All of which should give you plenty of sound-shaping potential - almost certainly enough to keep you going for 365 days. If, after this time, you want to continue using GTR Solo, you can buy a permanent license for $140.
The software is Mac- and PC-compatible and supports the VST, AU and RTAS plug-in formats.
