INSTALLATION INFORMATION

 

EMG MODEL: 

B125 ACTIVE BALANCE CONTROL / (ABC)

(PASSIVE/ACTIVE PICKUP INPUT) 

General Operation

The B125 Active Balance Control (ABC) is used to pan between two EMG-HZ pickups rather than use a selection switch. The B125 features input 

buffer amps for each pickup,  so if you have 2 Passive Pickups, 2 Active EMG Pickups, or are mixing an active with a passive pickup you can use 

the B125 Active Balance control. Pickups can be connected by connectors or hand soldered to the PC board. The control has a center detent 

(click) in its rotation. 

Installation notes:

The output impedance of the ABC is low, so the existing high resistance volume and tone controls will not work when placed after the ABC. 

The active tone control (VLPF) is required for tone. Any of the EMG Accessories like the  EXB, BTC or BTS Controls, BQC or BQS Controls, or 

OEM Models B30eq or B64eq can be added as well.
