Product Description

The Peavey 6505 Plus Guitar Amp Head features six 12AX7 preamp tubes and four 6L6GC power amp tubes, with presence and resonance controls and three-band EQ for taming their notorious tone.

Peavey proudly introduces its 6505 Series guitar amplifiers, named in celebration of Peavey's first 40 years, 1965 to 2005. The 6505 is also the relaunch of the 5150 Series, the immensely popular amplifiers Peavey designed with Edward Van Halen.

While known as the 5150, these amps became the undisputed go-to guitar amps for scores of rock, hardcore and metal bands due to their raw tone, relentless power and road-proven reliability. The 6505 is still the unquestionable choice for an ever-expanding list of endorsers, including 3 Doors Down, Ted Nugent, Atreyu, Steve Morse, In Flames, Arch Enemy, Visqueen, God Forbid, HIMSA, Darkest Hour, Sworn Enemy, Unearth and many more.

Very Nice!!!!!
What is your overall opinion of this product?
This amp is a beast!!!! everything about this amp is great. I purchased this amp with a Marshall 1960 A 4x12 loaded with Celestion g12-75 speakers and the combination is perfect. I tried this amp for 2 weeks with the EVH 5150III 4x12 and that cab is very "honky" in the midrange and has an overly bright top end, soloing was harsh sounding but the rhythm was chunky sounding. The Marshall cab is a perfect match with a singing lead tone and an aggressive crunchy rhythm. This amp is also extremely quiet at full gain unlike the original 5150 that I had years ago that had the high gain "hiss" no need for a noise suppressor with this amp. Made in the USA. I bought this amp for its incredible tone and because of the trouble free performance that I had for 12 years before trading my original 5150 in on a new guitar.
