“Driven by a powerful new BOSS DSP engine, the GT-100 is the most advanced GT ever, loaded with newly developed, ultra-responsive COSM amps, updated effects with enhanced real-time control options, dual displays for easy sound programming and more.”
BOSS hasn’t simply updated the GT-10 with a faster processor and a new lick of paint (though the GT-100 has both of those things); it’s gone back and completely re-modelled all of the presets, redesigned the interface and added a heap of nifty extras.
Essential tech specs:
Digital amp-modeller and multi-fx unit with two quarter-inch outputs, external fx loop send and return, amp control jack, USB and midi connectivity, headphones output, 3.5mm aux in (for MP3 players etc) and 400 program memory slots (200 user, 200 preset).
