I recently purchased the Radial Engineering Bigshot I/O switch box from Shoreline. This switcher does what I expected it to do - it quietly switches between two different guitar inputs. It also includes a handy mute switch. The output can then go straight to an amp, or through a DI box, then to the amp. There is no sound emitted when switching instruments and the box doesn't require a battery. The foot switches and the overall construction seem to be heavy duty/well made. This box is a great addition to your gear bag...and the Shoreline price and super quick delivery are a real plus - I received the box within a couple of days of placing the order!
