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.

"Ampeg enough said"

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.
