Critic Reviews

dbx 166, 166A, 166XL

ovnilab.com

The DBX 166A Comp/Limiter is a nuanced choice for musicians, offering potential vintage charm with caveats. While the older 166 models might provide more richness at certain settings, they come with noise issues and aging components. The 166A strikes a balance, possibly outperforming the XL model with slightly better sound and lower noise, though results can vary widely based on settings and unit condition. Despite its versatility and ruggedness, the 166A might require refurbishing, and its peak limiter is more of a distortion effect. Overall, it's a decent value if found at a good price, but not a standout without potential upgrades.
