Ampeg SVT-3PRO Bass Amplifier Head (450 Watts)

Step up to Ampeg's most popular bass head, packed with 12AX7 and 12AU7 tubes. Dial in your tone with the 9-band graphic EQ and 5-position midrange switch.

Boasting hybrid tube and solid-state operation with incredibly deep tone-sculpting controls, Ampeg's SVT-3PRO bass amplifier head may be an easy choice for players who have a hard time deciding on a tone they like best.

Intuitive, Deep Controls

There's no shortage of tone adjustments a bassist can make on the SVT-3PRO. Starting with the traditional gain, treble, middle, and bass knobs, this head offers a bright switch for instant boost or reduction in treble. A five-way frequency knob gives you five different center frequencies for the midrange control, further expanding the amp's tonal vocabulary. Finally, the amp's 9-band EQ ensures that even the most finicky of tone enthusiasts will find the ideal sound for any situation.

Switch Between Decades of Sounds

The head's tube gain knob controls how much voltage is driven into the tubes. With the knob tuned completely down, the tubes receive 100 volts, making for a compressed tone reminiscent of classic all-tube bass amps. Cranked all the way to the right, the amp delivers 300 volts to the tubes, making for a faster sonic response more akin to modern solid-state amps.

Quality Sound Starts with Quality Components

The SVT-3PRO is built for professionals seeking the ideal hybrid experience and sound. With a multi-tube preamp consisting of three 12AX7 tubes plus an additional 12AX7 and 12AU7 for added power and a power section driven by a solid state MOSFET transistor, it has a solid foundation to start from.

Ampeg read more also included Neutrik speakON outputs for improved conductivity with speakers. A mute switch is accessible by the front panel or footswitch and makes changing between instruments a seamless, pop-free operation. Variable speed fans adjust to the temperature, making for efficient and effective maintenance.

Ampeg SVT-3PRO Bass Amp Head

The Ampeg SVT-3PRO features a multi-tube preamp (not a single 12AX7 like many competitors), 5-position mid frequency selection, and Neutrik Speak-On(r) 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. It's no wonder, with its balance of great tone, serious power, and surprising affordability, that the SVT-3PRO is Ampeg's most popular bass head.

Pro Series heads are built for the long haul. The units remain cool with variable speed fans that only turn as the temperature dictates. DC supplied filaments ensure noise-free tube performance. And the 1/8 in. thick extruded aluminum front panels not only allow safe racking, the contoured fronts have an awesome look.

Features:

- Input Peak LED
- Input Pad and Bright Switch
- Mute Function

Welcome to the pros. If you are looking for that classic sound with the built in ability to dial in any tone, this is your head. As a professional musician that plays a lot of shows the fact that it fits inside a rack is great. Setup is a breeze, I have all of my road gear in a rack, just plug in the matched Ampeg classic 4 10 cabinet and your good to go. 10 min top set up/ break down time. Just remember to let those tubes warm up. This is the second SVT 3 I have owned. I had one early 1990's and it never let me down but it was made in USA. This unit is made over sea so time will tell the reliability. I have always carried extra tubes with me just in case but have never had to use them in a emergency. I change them out once a year. Love zZounds they are great pay and play get the gear you need now at a great price.
