Brother Cane “If This Means War”
It’s been 28 years, and “If This Means War” comes out of the gate showing zero restraint! Where some bands mellow with age, Brother Cane has sharpened their tools and bring a focused energy and drive to their signature sound. Bassist Glenn Maxey took his Spector Euro with LHZ into the studio, and this song shows it off well!
TonePump vs LHZ Preamp Comparison
This is an in-depth technical analysis and audio comparison of the TonePump preamp and the LHZ Preamp intended to provide objective data to help players understand the differences in tone and feel that they experience when switching between these two preamps.
Getting Funky with a CST!!
Bassist Paul McFadden recently upgraded his Spector CST from the stock configuration (EMG X-series P/J pickups and Legacy preamp) to the LHZ preamp with the new MID-03 Midrange control and a set of EMG PJ (CS) pickups. The challenge was that while the stock configuration was great for his traditional rock band, he needed a warmer tone for his funk / groove band.

Fede Delfino took a little time between tour dates to record a playthrough of “What’s Left Of Us” by Magnetico using his Spector Euro LX that he’d recently upgraded with LHZ Preamps.
Preamp Battery Comparison: Alkaline vs. Rechargeable
We often get questions about batteries from clients who are used to passive instruments: In this video we look at how preamp batteries discharge over time to answer these questions, and compare a standard Alkaline battery against a common NiMH rechargeable battery.
Solving Compact Wireless Noise Injection
If you find yourself getting unusual noise from your one-piece wireless transmitter on your guitar or bass, you may have a noise injection issue. Noise injection is most often noticed in ultra-low power preamps when using guitar transmitters that use a 3-conductor TRS plug. There are a few factors that can cause this: Compact one-piece transmitters use the RING and SLEEVE of the plug to recharge their internal batteries when docked. This requires an electronic circuit to monitor the RING…
Wireless Transmitter Noise Remediation
SYMPTOMS: You are experiencing unusual noise when a wireless transmitter is used. The noise can be anything from static, hiss, high-frequency whine, pops, clicks, dropouts, or audio fading in and out.
CAUSE: Wireless transmitters that use a 3-conductor TRS plug can cause noise issues.
Legacy vs LHZ Preamps
We’ve had several users report that the new Legacy preamp is somehow slightly darker sounding than the Hazlabs on their NS2, and ask if the LHZ preamp would resolve that. One client shipped us their Legacy preamp so we could conduct testing to compare the Legacy to the LHZ.
New for 2025: The LHZ-04 Preamp
The LHZ-04 preamp is a physical re-design of our current LHZ-03 model. It is the same circuit, same components, and same sound. Improvements for 2025 were driven by a significant number of clients using the LHZ in non-Spector basses with very confined control cavities. With smaller board dimensions and extremely low vertical clearance requirements, the LHZ-04 is THE choice for challenging installations.
This video walks you though the differences between the LHZ versions.
