LHZ-03 HazLabs Preamp Clone

Product Description

The LHZ-03 Bass Guitar Preamp is a faithful re-creation of the circuit used in late 80’s and early 90’s HazLabs bass preamps to create that classic and elusive Spector tone. If you have a 20-year-old Spector NS2A, Euro, or ReBop and are ready to upgrade the stock EMG pickups and TonePump preamp to get that signature NS2 sound, all you need are a set of active EMG PJ pickups and this preamp!

The LHZ-03 is a component-level clone of the original 80’s and early 90’s HazLabs preamp which was designed to push its opamp into nonlinear operation only during the extreme peak signal transients that occur when the bass is played aggressively.

Played with a normal or light touch, the preamp provides a clean bell-like tone. But, when played aggressively, this preamp provides a subtle tubelike compression and adds distinctive high-frequency harmonic overtones to the sound that perfectly accentuates the Spector growl.

WHY THIS PREAMP WORKS SO WELL ON SPECTOR BASSES

The EQ curves of the LHZ preamps faithfully replicate the original HazLabs EQ curves that augment the unique pickup placement on Spector NS2 basses. On the NS2, Rebop, and Euro bass models, both pickups are closer to the bridge than traditional basses, resulting in slightly lower volume and lower bass response. As a result, players would “dime” the bass and treble controls to compensate… and found the secret and elusive tonal artifacts that keep this vintage preamp design in high demand 30 years later.

The result is a deep (but tight and articulate) bass tone with a distinctive growl, light compression that keeps slap bass transients neatly in the pocket, and shimmering high frequency harmonic overtones that make the bass stand out in any mix.

EMG vs LHZ Comparison

The LHZ-03 preamp has been designed as a very compact 29mm X48mm PCB (Printed Circuit Board) that can be installed in the smallest control cavities. The PCB also allows multiple wiring installation variations to allow users to configure their unique volume, blend, and tone controls to suit their needs.

Product Specs/Additional Information

WHAT YOU WILL RECEIVE

One LHZ-03 Preamp with pre-wired bass and treble potentiometers (100K Linear Taper, Center Detent) and DuPont-compatible pin headers that are compatible with EMG modular controls using quick-disconnects,
A complete set of DuPont-compatible connectors with flying leads that provide easy connection to soldered pickups, volume pots, and output jacks,
One 9-volt battery connector wired to a 2-pin DuPoint-compatible connector.
3M Foam tape to mount the preamp securely in the control cavity, and
A downloadable PDF Installation Manual (link below) that contains multiple wiring diagrams for common installation scenarios,

INSTALLATION INSTRUCTIONS / OWNERS MANUAL

Looking for the manual? No problem! Click the WIRING DIAGRAMS link in the top menu, or just go straight to the LHZ-03 manual selection page here: LHZ-03 Installation Diagram

NOTE: SOME ELECTRONICS EXPERIENCE REQUIRED

Preamp installation is intended for users with some electronics experience. While the preamp is designed to be as plug-and-play as possible, some configurations may require soldering the included quick disconnect cables to traditional hard-wired volume pots and barrel jacks.

LHZ preamps have the bass and treble pots prewired, but you will need to connect your existing volume pot, power, and output jack using DuPont-style connectors to the dedicated pin headers on the PCB. The LHZ preamp will connect to EMG quick disconnect pots using EMG cables, or you can use the supplied flying-lead connectors to solder to hardwired pots.

We recommend you download a copy of the Installation Planning Checklist to help you plan and execute your installation.
