Ampeg
The absolute reference for bass amplifiers. The Ampeg SVT is the sound of bass in rock, metal and funk, from Woodstock to today's stages.
About the brand
Ampeg was founded in 1946 by Everett Hull in New York. Ampeg started with an innovative design: a microphone integrated into the double bass endpin, which gave the company its name (Amplified Peg). Over time, Ampeg evolved towards conventional electric bass amplifiers and became the reference brand of the sector.
The SVT (Super Vacuum Tube), launched in 1969, is the most influential bass amplifier ever built. With 300 watts of valve power and six 6L6 power valves, the SVT defined the sound of bass in rock: fat, powerful and full of harmonics. From Woodstock to today, the SVT has appeared on the world's most important stages and studios. John Entwistle of The Who and Geddy Lee of Rush are two of its most celebrated users.
Ampeg also manufactures the BA solid-state combo amplifier line and the Heritage SVT high-grade versions of the classics. The brand has gone through several owners including Loud Audio and continues to be the first choice for professional bassists worldwide.
