Love the BOSS GT-100!!

March 10, 2013

The flagship GT-100 is an excellent multi effects processor. It is light years ahead of the GT-3 I upgraded from. The unit has all new sounds and its operation is much easier too. No more push button / dial menu nagivation. The unit has 2 big LEDs to show what's going on and everything is controlled through knobs. It even has a looper built in. Firmware and all your patches can be updated via USB. This unit will keep me busy for many years to come.
