Frequently Asked Questions

The 1176 is far more aggressive and fast. The WA-1B offers a gentler, more rounded compression, prioritizing warmth and harmonic richness over transient shaping.
While marketing can sometimes exaggerate this, the discrete hand-wired nature does contribute to a more nuanced and organic sonic character, avoiding the sometimes sterile quality of PCB-based designs.
While usable on drums, the slower opto design won't handle snappy transients as well as a VCA compressor; it excels on instruments needing subtle glue and warmth, like vocals or guitars.
