Key benefit: Play without the guitar back dampening vibrations, allowing more body resonance and a louder overall volume. Simple, practical structure for everyday use. Soft, adhesion suction cups: Transparent rubber suction cups attach to the guitar body with strong adsorption. Use together with a density EVA pad that is very soft and flexible. Curved design reduces pressure on the instrument. Metal bracket support: A metal bracket provides stable support for the guitar body when you are playing while seated. Adjustable height and angle: A rubber knob lets you adjust the height and angle of the guitar support. Tighten the knob to lock the position, then attach to the guitar surface. The suction cup is replaceable, extending service life. Use scenarios: Sitting practice or performance: Install the suction cup on the guitar body and use the bracket to keep the guitar stable, freeing your back and shoulders for comfortable, extended playing. Recording sessions: Adjust the height and angle for an playing position and consistent hand posture, while preserving natural guitar resonance. Quick setup or travel use: Replaceable suction cup simplifies maintenance and prolongs life, making it easy to set up on the fly for informal jams or studio setups.
