I bought this pedal to be able to switch between my amp and my only amp + amp singer's guitarist when he does not play guitar on some tracks, eliminating the effect of loss of dynamic live. Many pedals can switch between two amps, this is the case of the little dual. However, they do not like the fact that dual SGoS pedal, to play two amps simultaneously from a single guitar signal. Several shops I recommend this pedal I trust and I was not disappointed. The quality is to go ... nothing to say.
I separated because our singer is now focusing solely on vocals, but it's still a very good tool
