Build Quality
When it comes to build quality, Strymon has a stellar reputation, and the Lex does not disappoint. The chassis is made from sturdy aluminum, giving it a premium feel. The knobs are smooth and easy to adjust, and the switches feel reliable. Overall, I would rate the build quality a solid 10 out of 10.

User Interface
The user interface is straightforward, making it easy to get started. The main controls include:
- Speed
- Mic Distance
- Horn Level
- Preamp Drive
- Dry Level
Each knob has a specific function, allowing you to dial in your sound quickly. The speed control lets you adjust how fast the rotary effect spins, while the mic distance influences the stereo width of the sound.

Sound Demo
Now, let's talk about sound. I used the Lex with various patches on my Nord keyboard, particularly enjoying the organ presets. Here's a raw sound demo:

With the Lex engaged, you can hear a lovely subtle swirl. As I increased the speed, the effect became more pronounced, creating a rich texture. The mic distance setting proved crucial, altering the stereo field from narrow to wide.

Experimenting with Different Sounds
While I primarily used the organ sound, I also experimented with piano and synth patches. Each produced unique results:
- The organ patch sounded full and rich.
- The piano patch offered a crisp and bright tone.
- The synth patches brought a modern twist, adding depth to the sound.
Here's how it sounded with a Rhodes patch:

Wrapping up, the Strymon Lex is an impressive rotary pedal. Its excellent build quality, intuitive user interface, and versatile sound options make it a strong contender for any musician's pedalboard. Whether you're a piano player, synth enthusiast, or guitarist, the Lex has something to offer. If you're in the market for a rotary effect, I highly recommend giving it a try.
