The Ultimate Bass Amp Head

Honestly, the Ampeg SVT-4PRO Bass Amplifier is probably the last bass head you'll ever need. If you're a gear freak, by all means feel free to buy a few more -- but this Ampeg really does deliver some of the greatest power, tone, and flexibility you can get.

Impressive Tube Complement

The Ampeg SVT-4PRO wants to impress you. So it starts with 3 x 12AX7 tubes in the preamp to generate a rich and powerful tone right from the get-go. Then, your sound grows in amplitude through the power of the MOSFET amplifier inside.

Tuner Output, and Other Thoughtful Details

The input section offers a single 1/4-inch input with a Tuner Output right beside it for quick and handy tuning on-the-fly. There is also a handy Mute switch right on the front, so you can change instruments without subjecting everyone's ears to the ol' pop and hum.

Astonishing EQ and Tone Control

Ampeg has outfitted this bad boy with a Control section, a remarkable 9-band graphic EQ for fine-tuning your tone. An additional 3-band frequency adjustment has a separate 5-position frequency target knob for the Midrange, giving you 5 times as much control over this critical dimension of your sound! There are also Gain and Compression knobs, and a Control for the Crossover point -- so you can put the SVT-4PRO's dual power amps to work, sending high and low frequency ranges to two separate cabs.

Enough I/O to Make Your Head Spin

The SVT-4PRO's rear panel offers one of the most sophisticated I/O sections on any bass amp available today. It starts with 3 x 1/4-inch input FX Loop, allowing you to run your loop in Stereo or Mono modes. There is a second Tuner Out on the rear. The Transformer Balanced Line Out section has both dedicated XLR and 1/4-inch outputs for Stereo or Mono use, along with a switch to bypass the onboard EQ when you want.

The SVT-4PRO's Speaker Output section includes 2 x Neutrik SpeakOn locking connectors for excellent conductivity. There is also a Mono Bridge Bi-Amp output, along with 4 x 1/4-inch outputs running at a 4 ohm optimal impedance. Power amps A and B, delivering 490 watts apiece, each have independent 1/4-inch inputs and outputs. When's the last time you saw such ridiculously comprehensive I/O on a bass amp?

Excellent Construction Throughout

On top of it all, the Ampeg SVT-4PRO is built for serious endurance. It incorporates super-high-quality components, including quiet variable-speed fans to keep it running cool. The front panels are cut from 1/8-inch thick aluminum, to look cool and withstand use and abuse -- whether you're using your SVT-4PRO a rack or as a standalone unit.

- 3 x 12AX7 preamp tubes
- Stereo or Mono FX Loop

Product Description

The sound is in your head. You've played countless instruments in search of the ultimate soul mate. Now you need an amp that will speak your sound to the audience. That's where the Pro Series heads live. The Ampeg SVT-4PRO head features multi-tube preamps (not a single 12AX7 like many competitors), 5-position mid frequency selection, and Neutrik Speak-On connectors that lock and provide better conductivity. A Mute button lets you change instruments in the middle of a set without the annoying "pop," and a Tuner Out jack that stays active even with Mute button on. The Ampeg SVT-4PRO is built for the long haul. The SVT-4PRO remains cool with variable speed fans that only turn as the temperature dictates. DC supplied filaments ensure noise-free tube performance. And the 1/8-inch thick extruded aluminum front panels not only allow safe racking, the contoured fronts have an awesome look. The 1200-watt Ampeg SVT-4PRO is the industry's highest powered bass amp. Your creative mind now has the palette to deliver the goods.

Customer Reviews
4.5 out of 5 (79 ratings) Rate and Review This Product
"Why would you use anything else?"
Sound: This amp has TONES of TONE!! I've had mine for four years now and play usually two shows a weekend sometimes four. No Joke. It still has so much volume, and I'm not referring to loudness which is without question loud! I'm referring to the expanse of the concussion and reverberation of the bass. I always say I don't play this bass, I feel it! On a normal basis I use the PR410HLF cab but when I really need to kickstart the earth's core and make everyones amps almost fall over I'll pair it with the SVT-410HE - Forget about it! Feature: I love being able to control my mainline out and stage volume seperately, EQ works great, Compression, I keep low bout 1/4. Brightness really does just that. Ease of Use: It's all right there. Not complicated or full of gadgets. It's a Bass amp, ya just gotta find your tone. All I've added was a KORG Tuner and the BBE. Set it and forget it. Quality: It's a MAC Truck, has taken disturbing drops in the rack but never a glitch. Value: Not cheap but ya get what ya play for. Manufacturer Support: ? Support for what ? Happy customer from the first day I rattled the house. The Wow Factor: Great looking in the rack. Overall: If this keeps performing a well as it has I don't see a need to look into anything else other than add another SVT IV Pro for the Festival and stadium stages. I and everyone else love this amp, the compliments are endless.

zZounds has verified that this customer bought this product from us. "Great Amp - You won't need another amp ever!!"
Overall: I've had my eye this amp for quite some time, saw the special 12 month pay plan and decided to take the leap. I've heard this amp in action and it sounds great Mono Bridged @ 1200 Watts RMS with a Gallien-Krueger Neo 412 Cabinet - rated for 1200 Watts RMS all night long and 2400 Watts Power Handling! I'm still trying to get a hold of the Gallien-Krueger Neo 412 Cab. I wish zZounds.com would carry them. Listen, you can't go wrong by buying an SVT-4 Pro Bass Amp. You can really feel the power of this amp.
