Carina Electronic Drum Portable Drum Rechargeable Built-in Speaker Foot Pedal Earphones Japanese Instruction Manual I bought this new on Amazon last year for 6,980 yen to practice drumming for the first time while waiting for my electronic drum set to arrive. I've only used it once, as a beginner. It's nice that you can listen to the sound while drumming with earphones, so it doesn't bother anyone. Price not negotiable.
