The Peavey Rage 158 15W Guitar Amplifier features 2 channels and 2 radically different voicings — Modern and Vintage. The Modern position maintains a warm, standard voicing while the Vintage position adds a hint of brightness to emulate some classic amp designs. Pre and post gain knobs, 3-band EQ, a headphone jack, and a tape or CD input make this hard-hitting little amp perfect for back porch jamming or solo practice.
