Peavey Solid State Professional Bass Amplifier.
Although the DeltaBass of 2000 offers only 160w. Anyone that laughs at this amp is probably
very inexperienced. Sure there are amps with more wattage, some are NOT continuous wattage as
is this amp, but few offer "clean" wattage as does this amp.
The DeltaBass has the most needed connections, front and back. A simple "in" for the ax
of your choice, with a parallel no juice "outplug" for your tuner. It also includes a sound
man's favorite, a three prong "mic" type male plug for the PA system input.
Some of the controls are VERY reliant upon the settings of an adjacent control knob. The
DeltaBass has a set of seven twist type knobs that cover equalization and volume. They dip
into the minus and plus ranges effectively.

When I saw the near perfect layout of the DeltaBass, I knew, quickly, that it would be in
my possession soon. Only experience could possibly know what experienced players want. I
think maybe there are some musicians in tow on the design aspects of the DeltaBass amp.
Within seconds I found the perfect tune collaboration settings for the particular song/sound I wanted. The one thing that impressed me the most was; the perfect pitch delivery
from in to out of the amp. No variance because of lame circuitry. I have used many other
amps in my years, never ever have I had such perfect delivery of the bass note. In other words; If you pluck a "C" note in 440, it comes out the rear of this amp in 440. I have had
variances with other amps. This amp has impressive clarity.
I didn't really need the owners manual with this amp. It is self explanitory!

I play a variety of music styles. The DeltaBass is flexible enough to be a switch-style
amp. I have even heard of folks using it for voice. Though it only has a 3+2 effects band,
the range within these controls is more than adequate for a full parimeter of styles.
I use a Peavey 5 string fretless, a Gibson RD Artist, or an Alvarez flat-top Bass to find
the sound I need for a particular event. If I need sustain I use the Gibson's active electronics that are built in. If I need the lower "B" register, I use the Peavey 5 string, for the softer sounds, of course, I use the Alvarez flat top.
Only slight and quick adjustments are needed to achieve my desired output sound. More
lows and less treble are my most common desires for the Country/Blues sounds. While on a
pick-me-up song might need a twist of the high eq. This amp is quiet until called upon.

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)!
Power:
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.
