The Sadowsky Onboard Bass Preamp (4-Knob System) is a completely prewired system offering the same controls and the same legendary active preamp as all Sadowsky basses. This preamp is designed for installation on most basses with a 4-Knob Layout. On newer active electric basses with a 4-knob layout 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. This system is not compatible with active pickups requiring anything else than a 250K or 500K volume or balance pot.prewired onboard bass preamp for electric basses with 4-knob layout, side jack and battery compartmentactive preamp for passive pickups4 knob layout with controls for Master Volume / Balance / Vintage Tone Control (P/P) / Treble and Bass (stacked)push/pull function at VTC knob for preamp bypassincl. 0.1 µF replacement capacitor for the VTC module for improved treble roll-off when used with Sadowsky Soapbar pickupslonger cables between the potentiometers to facilitate installation in non-Sadowsky bassesscrew terminals on the balance potentiometer for pickup hot & ground wires for solderless installationwithout Control Platefrequency response 5 Hz - 50 kHzBass control offers +18 dB boost at 40 Hz Treble control offers +18 dB boost at 4 kHztotal harmonic distortion (THD) 0.18% at 1 kHzpower supply via one 9V battery (Operating with 18V is not recommended, as this could destroy the circuit)current draw 9 mAup to 870 hours battery lifeinput impedance 1 Mohmoutput impedance 1 kohmNote: Defects or damage caused by improper installation or the use of unsuitable accessories and tools are excluded from the warranty.

The MPB2-918 is a dual channel buffer preamp. One channel has a high impedance input for use with a piezo or microphonic transducer. The other channel provides isolation and boost for magnetic pickups and features adjustable gain allowing you to boost the input signal up to 12dB (4X) while maintaining flat frequency response. It is less than ½ the size of a 9-volt battery making it ideal for instruments with limited cavity space. The MPB2-918 provides a strong output signal and isolation from external equipment that may otherwise adversely affect pickup tone. The kit includes a blend pot for mixing the magnetic and piezo signals into a common output for connection to an EQ preamp or direct to the jack. The MPB2-918 is ideal for providing excellent tone from an instrument with 2 magnetic pickups and a piezo bridge pickup. Both channels deliver clear and transparent sound with extremely low distortion. Like all of our preamps, the MPB2-918 is internally shielded to reject electromagnetic noise and includes internal filters to block AM and FM radio on the inputs. Bartolini set the standard of fully sealing the sensitive electronics. We use professional double tin plated pure copper wire with durable semi-rigid insulation. This ensures the 4 pre-stripped wires dont flop around in the cavity and the wires dont cut through the insulation over time. It can be used with either a single 9-volt battery (9-volt operation) or two 9-volt batteries wired in series (18-volt operation) for double the (6dB extra) headroom with no tonal change.dual channel buffer preamp for guitarstrong output signal with isolation from external noisesuitable for combination of Piezo pickups and magnetic pickupsflat response for the Piezo channeladjustable gain for the magnetic channel up to 12 dBinput impedance magnetic channel 1 MOhminput impedance Piezo channel 3.3 MOhmsupports 18V operation for 6 dB extra headroom power supply via 1 x 9V / 2 x 9V (18V) battery (not included)dimensions (L x W x H) 26.7 x 20.1 x 10.9 mm / 1.05" x 0.79" x 0.43"incl. 25 kOhm blend potWarranty Information for Electronics: Electronic components such as preamps and circuit boards by Sadowsky, MEC, Seymour Duncan, and Bartolini are covered exclusively by the legal warranty period.

The Bartolini MK1 preamp is an onboard active 3‑band EQ system found in production basses from Ibanez®, Cort®, and Lakland’s Skyline 44‑01/55‑01 models equipped with Bartolini MK1 soapbar pickups. Its design incorporates a push‑pull EQ bypass that disables the tone‑shaping circuit while keeping the signal buffered and powered by the onboard battery, allowing the bass to maintain output consistency rather than switching to true passive operation. Engineered to pair with Bartolini MK1 split‑coil soapbars, the system delivers hum‑cancelling performance and a broad tonal range.active electronics for electric bassBartolini MK1 on-board preamporiginal factory electronics in Lakland Skyline 44‑01/55‑01 and in Ibanez® and Cort® basses equipped with Bartolini MK1 pickupspre-wired 3-band preamp set with 5 pots1x volume pot (push‑pull for buffered EQ bypass), 1x blend pot, 1x bass pot, 1x middle pot, 1x treble potbuffered EQ bypass (push / pull volume control) - disables EQ but does not switch to true passive operationvoiced for use with Bartolini MK1 soapbar pickupspre-wired for 9 V operation (battery not included)Note: The return and refund policy does not apply to electronic components if their cables have been cut or soldered, if they show signs of use, if they have already been installed, or if there is other damage affecting the condition of the goods.

The NTBT is a 2-band tone control preamp with fully independent Bass and Treble controls. The voice is clear, transparent, and strong with wide boost and cut range for aggressive control. The NTBT features an adjustable gain which allows you to boost the input signal up to 12dB while maintaining flat frequency response. A professionally pre-wired and fully pre-tested harness saves the time and aggravation of wiring your preamp and pots into your instrument. Wired with our pro-level preamp and premium audio-quality pots and switches, youll have smooth control and be ready for years of rugged use. We include battery clips and an output jack for quick installation. All the pots are grounded with a wire that can be connected to the cavity shield or simply cut away if not needed in your installation.
