INSTALLATION INFORMATION

 

EMG MODEL: 

BTS SYSTEM

(ACTIVE PICKUP INPUT) 

A B O U T   T H E   B T S   S Y S T E M :

The BTS System is a complete control system for 2 Pickup Basses. Everything is included for installation into an instrument.  

Included in the system are:

1) Active Balance Control (B118)

The ABC Control is designed for EMG Active Pickups. It allows loss-free balance between two pickups and has a center detent for the middle 

position.  If you are using EMG-HZ Passive pickups, or other passive pickups you will want to use the B125 Active Balance Control which features 

buffered inputs for a higher input impedance. 

2) BTS Control (B100) 2-band equalizer for Bass guitar. The BTS 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 for the complete system are included.

3) Master Volume control, output jack, battery buss and clip.

Specifications for each of the EMG products included in the BTS System are available from the internet.

If you play the instrument very hard, and are boosting the bass or treble with the BTS, you should consider operating the guitar on +18 Volts 

(2 Batteries in series, see page 4). If you play mildly and use a minimum of boost the instrument should operate easily on a single 9-Volt battery. 

Use an Alkaline or Lithium battery for the best battery life and always unplug your guitar when you’re not using it.

Below is a diagram of the typical wiring order of the controls. Often the Volume control is closer to the pickups than the BTS Control making it 

difficult to wire the instrument. It is preferrable to have the Master Volume control last in the signal chain before the output jack. If this isn’t 

possible it’s no worry, either wiring order is acceptable.
