Feature:
an awesome feature is the foot switch. the foot switch rock because you can set your amp up for one smooth tone the kick in the eq for a sweet punchy tone, and when your done with a set you can just mute it and get off stage. for places you cant crank up your rig the direct out still gives you awesome tone. many amps that have direct out s@@k out all of your tone and leave you with a horrible sounding bass.

Quality:
this amp is made for the road. i travel full thime with it and it hasnt given me any trouble. i dropped the thing before and it barely made any marks on the amp, and still worked just as awesome.

Value:
this amp is deffinately worth the money. other amps may cost a little less but you wont get near the quality or the tone.

Desirability:
i personally think you have problems saying that an amp has sex appeal or that you could lust over it, but not too many other amps will give you the same tone for the money

Sound:
this is by far one of the best sounding amps out there. i travel full time with this amp and it has been incredible. the versatility rocks. you can get any where from hard puchy tones, to awesome rock tones, to an incredibly smooth tone. i would recomend this amp to a anyone wanting to get sweet tone, especially for the money.

Support:
to be honest support isnt the best. if anyhting should happen to your amp and you have to send it in, dont plan on having it back for a couple of weeks.

Overall:
to be honest if i had the money i would buy an svt classic head right now but for 5 or 6 hundred dollars less, nothing comes close.

Feature:
Good features, especially the on the back which allow jacking into house systems & recording equipment. The "Frequency" switch seems to make little difference in sound quality. But, I'm still experimenting with various sound settings.

Quality:
After about 50 hours of use, I had to get a tube replaced. But, it may have been due to bumbing, as well as the one bad tube from the factory that day. Since then (about 150 hours & several months), I've had no problems.

Value:
When I first got my Ampeg, I thought "This sounds great!". Everytime I play it,I hear from more & more converts saying the same. And the price has gone up on it since I bought it about a year ago.

Desirability:
My SVT-3 Pro head, along with my BXT-410HL-4 cabinet, give me a great, unbeatable sound.

Sound:
After one year I get a very clean sound with almost limitless sound quality options. Although with all of its options, you can get hiss by turning up the high frequencies too much. Best if you balance out the EQ with the guitar tones and cabinet adjustments.

Support:
I have not dealt with Ampeg directly, only the local retailer that sold me the equipment. And after some initial "who has the amp?" mixups, they were pretty good.

Overall:
This is a killer/ keeper system. I'm very satisfied with it.

I've played many bass heads in my time(46 years old) and you just cant beat the SVT3-PRO.Small but powerful for all style of music and roadworthy.Sound shaping is far better than SWR.I have had SWR,Hartke,small Eden and then back to Ampeg. Get it you will not be sorry...

Feature:
Alot of options.

Quality:
SLM manufactured in St. Louis Mo. The best made.

Value:
For the money, you get the power and tone!

Sound:
Everything that a bass player needs PERIOD!

Support:
TOTL> Top of the line.

Everything I've ever heard about ampeg is true.
I went down to the guitar shop and played this amp and it has everything you could ask for. And besides that a ton of good bass players are going to say that Ampeg is where its at.
