The BTC System, which is for EMG pickups only, features a pre-wired balance control (blend) and master volume with the bass and treble on a concentric pot.
BTC Controls and Systems are the most widely used bass EQ Systems in the world. Approximately 12db of cut and boost are available for bass and treble and all controls are center detented to assure quick return to normal tone settings. A dual-dip switch is mounted to the PC Board that lets you program the high end frequency response four different ways so you can choose the sound that's right for you.
These systems use the latest in surface mount technology, are extremely quiet, and require very little current from a 9 Volt battery.
- 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.
- BTC Control (B100) 2-band equalizer for Bass guitar. The BTC 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 BTC 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 BTC Control has a high input impedance and can be used with active or passive pickups. Bass and Treble controls are mounted on a concentric shaft and knobs are included.
- Master Volume control, output jack, battery buss and clip.
