Loud and lightweight design with versatile bass tone. That's what the new Yamaha BBT500-110 (10" speaker and compression driver) and BBT500-115 (15" speaker and compression driver) bass combos deliver. Both models incorporate the digital amplification and preamp technology from the new Yamaha BBT500H digital bass amplifier--with a speaker--in a single cabinet. The BBT500H is the first all-digital bass amp head, delivering 500 Watts of power (with two cabinets), and offering a total of 11 vintage and modern amp sounds ranging from a fat tube rig to a 1960's fuzz. It can be used with electric, upright or Yamaha "Silent" bass products, and has built-in dynamics and tone shaping capability.
