DIY LA2A

🌞 Build Your Own Classic Optical Limiter

Based on the legendary 1967 LA-2A signal path, this DIY kit captures that unmistakable warm, tubey compression that shaped the golden era of analog recording. The build is straightforward and satisfying—just follow the included bill of materials (not the silkscreen; a few minor quirks exist), and you’re on your way to classic tone.

There’s something magical about building and using a piece of gear that helped define the sound of hit records. Whether you’re tracking vocals, guitars, or drums, you’ll instantly recognize that smooth, musical glue that made the LA-2A a studio legend. Owning one is cool—but building it yourself and hearing it come alive? That’s next level.

🛠️ Beginner-Friendly, Tone-Rich Results

Even if you’re new to electronics, this project is absolutely approachable. With basic soldering skills, a little patience, and a careful eye on the bill of materials, you’ll end up with a studio-grade compressor and a deeper appreciation for the craft. It’s the perfect gateway into analog gear building—and the results speak for themselves.
