This is guitar amp modelling software: you connect your guitar to an audio interface connected to your PC/MAC and run the software, then rock out. Scuffham S-Gear is one of the best guitar amp modellers alongside Neural DSP.

The presets are excellent and can really bring the best out of any guitar you have. Great for home setups where you can't crank a boutique amp any higher than volume 1 or 2, let alone hitting the glorious highs of 11.
Includes 5 amps, 3 effects racks and now in V3.0, a drive pedal.
S-Gear is a collection of guitar amps, speaker cabinets and effects implemented in software for use with your computer, Windows PC or MAC. The software comes as a Standalone Application and as plug-ins for use with the most popular DAW (digital audio workstation) recording software.
Interesting - worth getting if already have some Neural DSP plugins already OP?
