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.

Warranty
All EMG Pickups and accessories are warranted for a period of two years. This warranty does not cover failure due to improper installation, abuse or damage. If
upon examination the pickup is determined to be defective, a replacement will be made. Warranty replacement products are covered by this same warranty. This
warranty covers only those pickups and accessories sold by authorized EMG Dealers. This warranty is not transferable.
