The OBP-1TK dual-band preamplifier allows you to "only" boost the upper (4kHz) and bass (40Hz) frequencies by 18dB while maintaining the character of your instrument. By using a FET circuit, the sound has a higher dynamic response and lower noise. The preamplifier's smaller size allows it to be installed in almost any instrument. The controls on the OBP-1TK consist of separate knobs for treble and bass.
- Maximum gain: 18 dB at 40 Hz (bass), 4 kHz (treble)
