Whether it’s and in-depth technical analysis, preamp comparison, tech tip, review, or just some inspiration that’s worth sharing, here it is!
LHZ Preamps have transitioned from the vintage LF442CN opamps to new chips. The LF442CN has been out of production for many years, and Hazlabs have moved to modern surface-mount op-amps a few years ago, so it’s our time to turn the page as well! This video is a blind comparison between 3 opamps: the original LF442CN and two of the new opamps that have been selected as being sonically indistinguishable from the original. Although we are calling this a “blind”…
In this video we answer the question “What happens to my active preamp when my battery dies?” This is a common questions from players buying a bass with active electronics for the first time. The good news is this: your preamp will NOT just die in mid performance! Instead, failing batteries just slowly fade out over many months so you have plenty of advance notice.
We had the opportunity to compare the circuitry, components, EQ response, and audio artifacts between our LHZ-01 and LHZ-02 preamps and a vintage HazLabs preamp (serial number 2029). We also had a KHaz clone and ran the same comparisons as well.
This is a quick audio comparison of the direct output of a Spector® Rebop DLX 5 with a PJ pickup set (EMG 40P5 and EMG 40J) after switching from an EMG BQC preamp to the LHZ-01 HazLabs clone. Bass audio is recorded directly into a MOTU M4, with both samples with the Bass and Treble controls at maximum. No effects or processing was done to the bass audio.
