The BP355 gives more sounds, effects, flexibility and control to bass players than any other bass multi-effects pedal for the money. Most bass players don't ask for much in the way of effects. We've gone to great lengths to ensure that whatever they will find everything they are looking for and more in the new BP355. Powered by the AudioDNA®2 processor, the BP355 features advanced modeling of 20 amps, 17 different cabinets and more than 70 different effects. Although the durable die-cast metal chassis of the BP355 is made for the stage, it is the perfect tool for virtually every bass player to perfect their playing. The BP355 has an additional input for your MP3 player, 60 different CD-quality drum patterns and 20 second looper players can use to jam, to practice, or to play along with. It also has a built-in tuner and expression pedal; the power supply is also included.
