This preamp is designed for installation on most J-style basses with a metal control plate. On newer active J-style basses with a side jack and a battery compartment, usually no modification is required. On passive basses, the only required modification is to move the output jack to the side of the instrument and to make room for a battery. The controls are: Volume – Pan (Balance) – VTC (Vintage Tone Control) – Treble \/ Bass. The treble and bass controls are boost only – flat response is with the controls at their complete counterclockwise position. The VTC control is passive, the maximum setting is a flat EQ. The further you turn the control down, the more the high end in the signal will be attenuated. The preamp can be installed either with the included control plate or mounted through a rear control cavity in either a 4-in-line or diamond pattern. This system is not compatible with active pickups requiring anything else than a 250K or 500K volume or balance pot.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003ePrewired onboard bass preamp for J-style basses with metal control plate\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eActive preamp for passive pickups\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e4 knob layout with controls for Master Volume \/ Balance \/ Vintage Tone Control (P\/P) \/ Treble and Bass (stacked)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePush\/pull function at VTC knob for preamp bypass\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCan be installed either with the included control plate or mounted through a rear control cavity\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFrequency response 5 Hz – 50 kHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBass control offers +18 dB boost at 40 Hz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTreble control offers +18 dB boost at 4 kHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTotal harmonic distortion (THD) 0.18% at 1 kHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePower supply via one 9V battery\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCurrent draw 9 mA\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUp to 870 hours battery life\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInput impedance 1 Mohm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOutput impedance 1 kohm\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eNote: Defects or damage resulting from culpable or improper installation as well as the use of unsuitable accessories or tools are excluded from the guarantee.
