Precise control
The single turn makes dialing in the exact resistance value very easy for my preamp project.

Great for pedal mods
Replaced the noisy pot in my overdrive pedal with this 10K version. Smooth adjustment and no crackling sounds.

Good quality
Works well electrically. The plastic cap fits a bit tight but stays on securely once installed.
