Boss’ high-end multi-effects processor is now even more powerful than before, adding a host of great new features to its already formidable arsenal. Two new amp types are included, along with cutting-edge mdp effects, an acoustic guitar simulator, and an improved rotary effect. A convenient guitar-to-midi function is on board as well, letting you connect to a computer to play soft synths and input midi note using your normal guitar. The gt-100’s usb audio capabilities have been expanded too, providing greater flexibility for re-amping applications. And with the boss tone studio software, you can now edit gt-100 patches from a friendly graphical interface on your computer.
