What we think of the Boss GT-10B
The Boss GT-10B is a professional guitar multi-effects processor loaded with revolutionary tools. It may look like a confusing piece of equipment but 15 minutes with the manual makes it seem very simple. The ability to program all your favorite tones along side the amp control capability used to switch channels on compatible amplifiers makes this pedal the most affordable professional model available.
It has 400 memory banks divided into 200 Presets and 200 User defined banks and an ultra clear LED display is very easy to see on a dark stage. If the GT-10B alone doesn't have enough pedal functions you can upgrade it with the Boss FS series pedals and Boss FV Expression pedal.
