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.
