Please note that the color of the product may look slightly different from the actual color. Please forgive any minor scratches or stains that could not be captured in the images.

We describe the condition of the product, such as if there is a significant feeling of use, such as if it interferes with playing. Please refer to the manufacturer's website, catalog, etc. for product specifications and details. You can practice without making sound from the speaker by connecting headphones, which is ideal for practicing at home at night. Controls: Volume, Treble, Bass, headphone jack (1/4" stereo phone). There is BASS to adjust the strength of the lower sounds and TREBLE to adjust the strength of the higher sounds. Start with both low, and if the sound feels thin, raise the Bass, and if the sound is muffled, raise the Treble. The more you raise the Treble and Bass, the more "scooped" the sound becomes. (Quoted from the internet.) The PG-10 is a compact size that is easy to carry around, and can be used easily anywhere. It has various controls, allowing you to adjust the sound quality to your liking. The robust exterior and mesh design speaker grill are designed to withstand long-term use. Thank you for viewing.
