With the device AMT Pangaea CP-100, you can easily emulate the sound of any guitar cabinet by loading different IRs (Impulse responses) of guitar cabinets in the device memory. Many different IRs you can easily find in Internet (both paid and free). In the device memory you can load up to 100 IRs and to use any one you want when playing guitar. When connecting CP-100 to PC, there is no need to use any special software, the device is seen as USB disk PANGAEA_MINI. You can also tune the sounding of the IR by volume control, by five bands equalizer and by using FX ROOM. You can pass the signal (without breaking signal integrity) from your tube power amplifier thru CP-100 to a guitar cabinet, and then you can process the signal by the IR and pass the signal directly to the input of a broadband sound system. This will let you to play without a mike set near a guitar cabinet.
