6.4mm vintage Guitar Knobs for AMP Effect Pedal Stomp Box 1/4" brass Precision fit shaft, pointer style, durable ABS with insert

Precision Grip Surface: Fine-knurled or matte-textured circumference gives consistent traction, letting you dial in exact settings with one-handed control and no accidental overshoot Low-Profile Panel Design: Short diameter and low height keep the knob close to the faceplate, reducing snag risk while maintaining easy reach for quick adjustments Even Turning Torque: Smooth internal interface delivers uniform rotation from start to stop, enabling accurate adjustments without sticking, binding, or loose play Durable One-Piece Body: Molded or machined as a single solid unit, it withstands repeated twist cycles, holding its shape and grip tension without loosening over extended use Full-Rotation Check: Before pressing fully, align the D-flat with the shaft's flat side, then push down evenly—spin through the full range to confirm free movement without scraping the panel
