That's the year that Ampeg designers Bill Hughes, Roger Cox, Bob Rufkahr and Dan Armstrong set out to build a bass amp like none that had come before it.The standard power level for bass amplifiers at the time was 50 watts, but Ampeg's team wouldn't settle for anything less than a monster. and Canadian English) or (thermionic) valve (outside North America) is a device generally used to amplify, or otherwise modify, a signal by controlling the movement of electrons in an evacuated space.However, tubes are still used in several specialized applications such as guitar amplifiers (also called a valve amp outside the U.On most tubes, the leads are designed to plug into a tube socket for easy replacement.The simplest vacuum tubes resemble incandescent light bulbs in that they have a filament sealed in a glass envelope which has been evacuated of all air.Although the envelope was classically glass, power tubes often use ceramic and metal.
With unprecedented power under the hood, the all-tube SVT shipped with a warning label that read: "This amp is capable of delivering sound pressure levels that may cause permanent hearing damage." Of course, the Rolling Stones couldn't ignore a label like that, so they became the first band to take the SVT on tour.The Infinite Baffle design of these sealed enclosures produces vast amounts of tightly focused bass.In the world of high performance bass cabs, the Ampeg SVT-810E stands tall and proud.This is the speaker enclosure people mean when they say SVT speaker cabinet. Other than the color scheme, it is identical to the original SVT-810. Ampeg learned early on that 10” speakers work much more efficiently than fifteens or eighteens—and if you put eight 10” speakers together, you can move a huge column of air.
You’d need five 18” or six 15” speakers to move as much air as the SVT-810E!Although the company specializes in the production of bass amplifiers (for bass guitars and double basses), they also manufacture guitar amplifiers.
