The Verdict
The dbx 231s is the sound engineer’s workhorse and the tone-sculpting obsessive’s dream. This isn’t a hi-fi toy — it’s the real deal, used in touring rigs and installed PA systems because it works and keeps working. 31 bands per channel means you have surgical control over every frequency range. Need to kill a 3kHz honk? Boost vocals in the 2.5kHz band? Tighten bass response at 60Hz? You’ve got the tools.
Build quality is where dbx’s reputation is earned. Heavy-duty faders, balanced I/O, and engineering that prioritizes reliability. Over 108dB of dynamic range means your signal stays clean and transparent whether you’re working with hot bass output or quiet acoustic signals. The dual-channel setup makes this uniquely flexible — run your guitar into one channel, bass into another, and EQ each independently. Or use both channels for stereo processing.
This is a professional tool. If you’re a live sound engineer, recording at home, or a player obsessed with tone control, it’s worth the investment. For bedroom practice and casual gigging, you’re probably overkill-budget.
