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.

Ioannis Sandalis : Ghost in the Ruins bass playthrough

Ioannis Sandalis posted this great video playthrough of “Ghost in the Ruins” by Savatage. We love this for a few reasons: Ioannis was inspired to swap out the electronics in his Rebop with an LHZ preamp as he was aiming to get that tone from the Savatage albums that were all recorded on a Brooklyn-era Spector. There’s a tone of tasty detail and articulation on the upper strings, so get the headphones out and enjoy!

Matt Baldwin LHZ-04 Review

Matt Baldwin is an independent recording artist at Mind’s Eye Recording Studios and bassist for the blues-rock band Teskey. He purchased the LHZ-04 to upgrade the stock preamp in his custom Spector and took it into the studio to record tracks for Teskey’s 2025 album “White Wolf.” Matt completely surprised us by recording a video review of the LHZ-04 preamp, which we are proud to share here! This video had us grinning ear-to-ear about halfway through when we got to…

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.
