The Peavey VYPYR VIP is the first amplifier that contains Electric guitar, Bass guitar, and Acoustic guitar amp models. Now for the first time ever using our Variable Instrument Input, a single amp can provide amplification for a variety of instrument types. Not only does the amplifier morph from a bass amp to an acoustic amp to an electric amp, it also (for the first time ever in an amplifier in this category) allows the electric guitar player access to instrument models as well.
