6505® II Guitar Amplifier Head
Peavey's genre-defining high-gain legacy continues with the 6505 II guitar amp head. Like the original 6505 head, the 6505 II offers two (2) distinct channels. This time, however, the 6505 II adds separate EQ, Resonance, and Presence controls to each individual channel. These added features give you more control and flexibility over your sound and power output. An upgraded footswitch provides easy control of channel selection, effects loop, and Crunch features. Now you can instantly access that extra gain in the Rhythm Channel with your foot and never have to take your hand off the guitar. With the expanded power and features of the 6505 II guitar amp head behind you, unleash your signature sound in the studio or on stage.

A 2-channel monster
Enjoy customizing your favorite tones with channel-specific Pre-Gain, Post-Gain, Resonance, and Presence knobs that allow for extensive sonic manipulation. Ride the glassy crisp-clean rhythm tones or stomp the crunch to unleash the stadium-shaking overdrive you expect from this beast of an amp. Tap into endless sustain and let your tones ring throughout the arena.
