A better angle

I designed flexFX to make tabletop effects more comfortable to use. The knobs angle toward the player, while the unit keeps a slim, compact profile.

A custom flexible printed circuit and 3D-printed TPU let the body bend and lock at an angle during use, then fold flat afterward.

The audio circuit is based on the classic Klon Centaur transparent overdrive.
