The Fender Acoustasonic 90 Combo Amp is a high-powered, portable acoustic amp that also accommodates vocal amplification via two independent channels. Capable of dishing out 90 watts of power, it's a booming 8" speaker with a high-frequency tweeter to gain some extra clarity for your instrument or your own voice. Its two channels can be controlled independently from each other, and both feature Volume, Treble, Middle, Bass, and FX Level knobs and an FX Selector for its built-in Vibratone, Delay, Chorus, and Tremolo effects. The first channel uses a standard 1/4" input, while the second has a XLR/1/4" combo input for microphones or another instrument. The Fender Acoustasonic 90 Combo Amp is the perfect practice amp for its size and power, but it also works great in a studio setting.
