Ampeg SVT-4 Pro - Price drop £550


Recommended Posts

Ampeg SVT-4 Pro for sale

Price reduced to £550

Mint condition aside from a few scratches on the underside and comes with a Gator 4U rack case and rear mounted rack fan. The amp is side vented so I drilled some holes in the side of the case in front of the amps exhaust fan and I have never had any problems with overheating. I bought it in 2014 and still have the sales receipt and manual although as you can see from the pictures of the back panel it was manufactured in 2012.

It's a beast of an amp which I'm sad to let go of, but as I don't need all of the features (bi amp etc), I bought a 7 Pro as I wanted something lighter and can't really justify keeping both.

If anybody would like more pictures or information please let me know.

Ampeg blurb:

In the world of high-performance bass amps, Ampeg’s SVT amplifiers are in a class by themselves. In true Ampeg tradition, the SVT-4 PRO offers you more power, performance and flexibility than any other bass amplifier in its class.

SVT-4PRO offers an expansive palette of tonal options. The Frequency control allows you to select the center frequency for the Midrange control, giving you five distinct voicing options for the Midrange. And if that’s not enough, you can use the 9-Band Graphic EQ to fine-tune your sound—or use it to set up a footswitchable “second channel” with a volume boost for your bass solo.

SVT-4PRO is designed for the player who wants SVT tone and performance (with a few modern enhancements) in a convenient, high-powered, rackmount design. With a huge diverse group of artist endorsements, including Tony Levin (Peter Gabriel/King Crimson), Cliff Williams (AC/DC), Pablo Stennett (Ziggy Marley) and far too many others to list here, the SVT-4PRO is a clear favorite among professionals. In the world of high performance bass amps, the Ampeg SVT-4PRO has what it takes to really define your sound.

Such a great amp. Tremendous EQ variations. Nice warm tube pre-amp. 

Had one up to a few yrs ago and loved the tone. Mine was an older 1993 one from US that i had transformer replaced for use on 230V. It was that good it was worth it.
