I connected it to an amplifier and tried to produce sound, and while it works, the sound is exceptionally quiet. It's not just a matter of thin sound; I think it needs repair. I bought it on Yahoo Auctions a while ago, and the sound was already quiet when it arrived, so I haven't used it since and it's just been sitting in my room. When I checked it for this listing, the frequency of the sound seemed to change when I stepped on it, although the sound was very quiet. The wiring is simple, so someone with experience in hobbies might be able to fix it, but I am a novice and offer no guarantee, so I am listing it as junk. Thank you.
