Amp Locker

This is one of the best guitar amp sims I've tried, particularly for my low performance laptop. It's worth playing around with for a while, because the controls work a little differently than you'd expect - 'gain' is pretty self-explanatory, but 'master' controls the amount of power amp saturation/clipping. This means that for e.g. a clean sound, you turn up the gain, turn down the master, and use the global volume control to set the overall level. The included Marshall amp is very good, but another free amp for clean tones would be welcome. The developer also offers some paid amps that can be demoed within the plugin itself, with the highlights being: Orale (crunch/lead), Paevy 5650+ (high gain/lead), Britone (crunch/lead), Califier (high gain/lead), and Dudemeister (clean/crunch). The only thing missing for me is a decent Fender clean amp, and perhaps a gain reduction meter for the rack compressors.
