Following the block diagram on the left, input-1 flows directly to the toggle footswitch while input-2 is equipped with extra features to address concerns that may arise, depending on what type of instrument is being used. This includes a TRIM circuit that enables the instrument to be padded down to reduce the level and a bright switch that lets you compensate for extra-long cables.

Keep in mind that the i/o is completely passive and therefore requires no power or battery. This also means that it will not boost a signal. Input-2's TRIM control could be used to reduce the level from an acoustic guitar with built in preamp, or active bass that would otherwise be much louder than their passive counterparts.

In instances when using two passive instruments such as maybe a Fender Strat® with single coil pickups and a Les Paul® with humbuckers, the single coil pickups will not be as loud as the humbuckers. This effect is often desirable and therefore, the TRIM would not be used. If however you had your system set in such a way that you would want both at the same level, such as during a direct recording session, you would engage the TRIM and introduce the bright switch to offset the effect of the potentiometer or length of cable. The BigShot i/o is designed to suit both true-bypass purists and multi-instrumentalists alike.

The BigShot i/o is also equipped with two outputs. One is designed for a tuner while the other would go to your amplifier. When the MUTE footswitch is depressed the output going to the amp is shut off to allow quiet tuning on stage. A selector switch allows the tuner to either be on all the time or be toggled so that it is only active when the footswitch is depressed. Some tuners introduce clicking noise from their quartz clock or can load down the guitar signal. For the purist, toggling the tuner when needed is preferred.

Connecting the BigShot i/o

Before making any connections, confirm your amplifier is turned off and the volume controls are turned all the way down. This will reduce the possibility of problems should you have a short or a bad connection.

Start by connecting your main guitar to INPUT-1 and your second guitar to INPUT-2. Now connect the OUTPUT to your amplifi er. If you have a tuner, you can connect it to the TUNER output.

Turn your amp on and test your setup at a low volume. By depressing the SELECT footswitch, you will be able to toggle between guitars. By depressing the MUTE footswitch, you will turn off the output for silent tuning. You are now set to go!
