The plugin is reactive to guitar volume (like real ones) and accepts a lot of plugins before (compressor, distortion, etc ...).
All filters are IIR to reduce the processing delay (less than 0.5 ms). Ideal for live playing. The cabinet simulation does not include room effect has usually found for this kind of simulation (its simulates only spectral characteristics of cabinet). So it sounds very dry if you hear it with a headphone, but it sounds better if you play it in a real room trough flat loudspeaker or in a mix.
Cabinet simulation can be turned off and you can add cabinet plugin with free pulses (i.e. http://lepouplugins.blogspot.fr/2010/12/lecab2-vst-for-windows.html) to sound has other amplifier simulator.
The version 1.4 is working at 44.1 kHz, 48 kHz and 96 kHz and includes a new convolution engine for with 2 x less CPU
