The Amp That Defined Bass Sound

Designed for players that want the familiar power and tone of an SVT but need the tone-shaping capabilities afforded by modern bass amp designs, the SVT-4PRO is a rackmountable bass head built for the touring pro. 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.

Ampeg SVT-4PRO Features:
  • 1/4" and Neutrik speakON outputs
  • Input peak LED
  • 3 x 12AX7 preamp tubes
  • Solid-state power amp
  • 3-band tone controls
  • 5-position midrange tone control
  • 9-band graphic EQ
The Ampeg SVT-4PRO - classic tone in a rackmountable amp!

It's Ampeg.

Fantastic Amplifier. I have used the Sansamp RPM for yearsand love it and now have it as a backup. There is nothing like an Ampeg Amp. The RPM is close but there is that toneyou just got to love coming from an Ampeg. The featuresand power is what I needed and this was the perfect fit.Easy to use and tons of tone options.

Unmatched performance & Reliability

Owned new since 2007 and it simply is the most user friendly roadworthy bass head ive ever owned! Masterful tones and easily contoured w all the controls you would ever need. Sometimes more then volume us bassists deman TONE first; this delivers! Used live on arena/festival size stages to small bars and clubs. Sound guys love the unbalanced XLR for running direct to the PA for those larger venues. Got compliments from national touring acts ;-)I know price can be beat by other models but not the construction or quality. Great across almost every style and genre. Not sure ive praised a piece of gear as much as I do this; Wont play anything Else! I own the 1200 very cool they have 3 models/versions to choose from now!

Power for days

This is a great amp and has no problem filling even large venues when paired with a 8x10 cabinet!
4.5/5

Workhorse

Look, we can sit here and argue what the best sounding bass head is all day, but in the end, it depends on what you are looking for. This head has great tone and power through a Mesa Powerhouse 4x10. I've been gigging with it heavily for 4 years with no troubles at all. Night after night I get huge bottom end (sound, I mean). I do use a seperate rack mount compressor. The onboard compressor just can't cut it.
