Why it exists
The smooth opto is perfect until the source needs edge — then smooth reads as buried, and you reach for EQ to fix what compression flattened.
EA-3A keeps the opto musicality but moves everything forward: ~1.5 ms attack, a ratio that steepens toward limit, presence voiced into the transformer stage, and odd-order grit when you slam it. Same two-knob workflow as EA-2A — a completely different animal.
In the session
- Put electric guitars in your face without an EQ pass.
- Tighten a drum room while the presence region stays lit.
- Slam it for grit that reads as attitude, not distortion.
- A/B against EA-2A — same design, opposite personality.
