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.
