Feature:
Tuner and mute button are very convenient!

Quality:
The last reveiwer had the same problem as me - a bad buzzing coming from the cabinet every time you hit a low D. I brought it back to the dealer who couldn't fix it( I don't know how hard they tried )so they gave me another new one. The new one is fine.

Sound:
Great Ampeg tone!

Ease of Use:
Very easy to use and dial in your tone.

Support:
Talked with them via email about the buzzing problem and they didn't have a clue what was wrong but at least they answered me.

Overall:
A very good amp but the buzzing problem was a big ordeal. I would avoid this amp unless you could try it before you purchase one to make sure it doesn't buzz.

Feature:
The style settings are helpful, but there's not much it needs to tweak the sound. I just wanted a good clean warm signature Ampeg sound. Not for everybody, but perfect for me. With the tube preamp, I can try out different brands of tubes and customize the sound even more.

Quality:
I noticed a buzzing when I hit a low D from the baffle when it was delivered. Could be caused by lots of things including transport. Still, a professional quality amp shouldn't be buzzing at all. I pulled the grille, found the cause (one spot on the woofer basket where it mounts to the baffle. Easily fixed, I reefed down all the screws I could find and it's as clean as can be now.

Value:
It ain't cheap. But it'll last forever. Way overbuilt and rugged. Inspires confidence.

Desirability:
Um remember, it says Ampeg all over it... Lots of cache

Sound:
Very warm, very loud, exactly the kind of tone that I'm addicted to. Luckily, I started with Ampeg, and have never looked back. This one is smooth in response from bottom to top. And, with the new tube preamp, I can crank the gain setting and the warmth just glows. Couldn't be happier, especially considering it's a combo.

Ease of Use:
Very simple. not a lot of extra stuff to play/distort my nice bass with.

Support:
An Ampeg tech has always e-mailed or responded by phone immediately. No problems, no wait. They stand by their gear.

Overall:
This will keep me happy for a long time.

Feature:
Pretty straight forward ,plugn play

Quality:
Ihave a little buzz problem but nothing catastrophic

Value:
No better combo for the Money ,i even annilates pricier competiters

Sound:
I have owned this badboy for six months and i am playing a 72 fender Geddy Lee sig Bass ,with a Ampeg SVT Vacume Tube Injection DI, and it rumbles when i hit my E and responds beautifully when i hit some melodic mid and high octives,i love it ,i Do have an Issue with my Casters staying plugged in when i lift the unit up and that was straight outa the box ,other than this ,i would recomend this badass to anyone seeking a beastly combo.Cheers.R

Ease of Use:
It takes a little play time to find your sounds but thats the funpart.

Support:
We'll find out ,i'll let ya know

Overall:
It is now an imparitive part of my Bass arsenal,have to get a new one,no better amp combo for the money.

Feature:
Not a lot of features, but a solid amp such as this does not need a lot of adjustments. I would like there to be a tilt back feature. The tuner is convenient.

Quality:
Solid and dependable

Value:
Priced a little high but delivers the goods.

Desirability:
Basic apperance. The diamond looks better. I don't think the quality is better though.

Sound:
I love the tone! Tone! Tone! Lots of head room. I love clean low end and this one has it.

Ease of Use:
operation is very easy and straight foward. Pure Ampeg.

Support:
N/A not needed yet......

Overall:
I think I will be happt with this after a very long search. I finally went with what I wanted all along.
