The SVT 4 Pro is the real deal. It has the "classic" tube preamp tone that made Ampeg famous with a host of modern updates and options. It has the following features: Dual Separate Power Amplifiers, Biamp Capable, 5-Position Midrange Selector, Compression Control, 9 Band Graphic EQ, Tuner out jacks, Speakon Jacks or 1/4" outs, stereo effects in/out, amp in/preamp out, and footswitch control (plus a whole bunch more stuff)!
1600 Watts Mono-Bridged @ 4 Ohms (1200 Watts Continuous)
1200 Watts Mono-Bridged @ 8 Ohms (900 Watts Continuous)
2 x 900 Watts @ 2 Ohms (600 Watts Continuous)
2 x 625 Watts @ 4 Ohms (490 Watts Continuous)
2 x 350 Watts @ 8 Ohms (300 Watts Continuous)

and it weighs almost 40 lbs


This amp has a lot of buttons, knobs and switches so there is a learning curve but once you get it figured out, this amp can do pretty much anything. You can dial in unlimited numbers of tones with the EQ or the bass/mid/treble and the adjustable mid. A footswitch allows you to click between them for 2 distinct sounds, just click away. The SVT-4 has a variety of output options. The stereo power amps can be biamped (with adjustable crossover), ran in stereo or used with just one output and a smaller cab to play at much more reasonable volumes (but still get that pushed tube sound). Of course you can also bridge the signal for a full 1600 watts of bass fury and bury the rest of the band. The amazing thing about the SVT-4 Pro is that you get so many options and never compromise quality.


Tone is why you buy Ampeg and this amp has it! 3 12AX7 tubes power the preamp to give it that warm "classic" low-end drive that Ampeg is famous for. You really can dial in pretty much any tone you want from a deep warm reggae sound to a driven tube metal thump. The owners manual has a few recommended settings including: Classic Ampeg, Funky Thing, Etheral Fretless, Jaco, R&B Groove, and Downright Upright Doneright. This amp IS the tone that all the modeling amps try to emulate.


This is the Cadillac of all amps. A really big, smooth riding, high powered, pimped out Cadillac!
