The Peavey VYPYR VIP 3 guitar modeling combo amp uses Variable Instrument Input technology to provide amplification for a variety of instruments. Not only does this combo morph from a bass amp, to an acoustic amp, to an elecric amp, it also allows the guitar player to access instrument models as well. Peavey uses a combination of powerful 32-bit, floating point SHARC processors and patented TransTube® analog circuitry to create one of the best sounding modeling amps available. All VYPYR effects, amp models and parameter controls can be accessed without plugging into a computer, unlike many other modeling amps. VYPYR's new USB bi-directional data and audio port provides an easy way to record, connect to VYPYR software, store presets, get lessons and play along to backing tracks. All of the revolutionary features from the original VYPYR series is here, plus more effects, more amp models and more instrument models.
