The "Yamaha Bass Amplifier VC25B" does not appear to be a product model; the closest match is the Yamaha VX25B, a 25-watt bass amplifier with a 12" speaker, high/low input jacks, a pull-gain volume, master volume, Treble/Bass EQ controls, and a reverb tank for its original 120V AC models. If you are looking for a different model, the company's products include the newer THR series desktop amplifiers, which offer digital modeling and a variety of tones, or various MA/PA Series and VC Series professional sound systems for commercial applications.
