1. Turn on your amp and slowly turn up the volume If all is working the next step is to set the DRAG control With DRAG at the 12 o clock position turning it clockwise will brighten the tone while counter clockwise will darken it Strum a chord and slowly turn the DRAG control until the tone matches that of a direct connection to your amp All that s left is to set the power boost gain Step on the BOOST footswitch and confirm the LED is on Slowly turn the GAIN control clockwise until the desired amount of signal boost is achieved The PB1 is now ready to use SIGNAL CHAIN PLACEMENT The PB1 can be placed at different points in the signal chain depending on the type of pickups and effect pedals it will be used with Places where the PB could be used include before long cable runs before a chain of effect pedals and before the signal is split to feed more than one input or amplifier As you add more effect pedals and patch cables to your signal chain you may start to notice your guitar sound becoming dull It may sound much more dull than it does when your guitar is plugged straight into your amp This high frequency loss is caused by high capacitance and resistance from the extra Passive Pickups Long Cable To Amp _ gt Radial Engineering BigShot PBI User Guide cables and jacks in your complex signal chain Placing the PB1 directly after the guitar and before other pedals can restore the clarity and impact l2.

6. ost to Capacitance Certain effects like delay flange and chorus can cause a drop in volume when engaged This happens when the pedal has a lower impedance when engaged than when bypassed A buffer before the offending pedal can solve this prob lem and keep your level consistant as well Some vintage wah wah and fuzz pedals require the guitar to be connected directly without a buffer in between This usually only applies to some vintage pedals If not sure if your pedals are compatible with the PB1 try connecting them in a chain with the PB1 as the first pedal If a pedal following the PB1 cre ates exccess noise or hiss it should be moved ahead of the PB1 in the chain The PB1 should be placed ahead of any passive splits in the guitar signal such as Y cables or passive ABY amp switchers Buffering the signal allows it to be split and sent to two or more devices like a tuner and a couple of amps without loading down the pickups For example the Radial BigShot ABY is a passive amp switcher that can split the signal three ways to feed two amps and a tuner as shown below Passive Pickups Radial Engineering BigShot PBI User Guide
