Here are the details from the EMG website: The BTS System is a complete control system for EMG bass pickups. It includes an Active Balance Control that allows for loss-free balance between two pickups and has a center detent for the middle position. The additional BTS Control is a 2-band equalizer that features single-pole filters for broadband equalization. Often the broader single-pole filters are preferred for musical instruments because they are less selective, easier on the ear, and sound more “musical”. One of the features of the BTS Control is a 2-position dip-switch that controls the slope of the high frequency response. By choosing one of the four combinations the high frequency response can be tailored to your liking. The BTS Control has a high input impedance and can be used with active or passive pickups. Bass and Treble controls are mounted on separate shafts and knobs. Also included are a Master Volume control, battery buss and clip.
