Feature:
The built in tuner ROCKS!!! Not only is it a handy feature, but it is also very accurate. Stacks up in accuracy to the low end Peterson. The built in effects are for the most part usable, some more so than others. Others need a LOT of help. Behringer are you listening??? The Rotary: Throw it away!!! I am a former Vibrotone user, and let me tell you, not even close! Back to the Drawing board.

Quality:
Quality?????.........I own 2 other pieces of Behringer equipment, and all 3 of the will still be around long after I am dead. By the way, I am only 43! Enough said!

Value:
If not for the few shortcomings, the rating would be a 10.

Desirability:
Clean lines, easy on the eyes, easy to transport. easy to set up and tear-down without having to use a boat-load of externals

Sound:
With the advent of modern technology, new "sonic miracles" are happening every day. The amp does have somewhat of a tube-like presentation, and response(due to the ever increasing use of FET transistors), but my main gripe is the Jensen 1035 speaker. The amp is rated at 30 watts RMS. The speaker however is rated at 35 watts RMS @ a very odd 4 ohms, for an amp of that size. If you want more sonic flexibility buy a higher rated speaker, or use a higher rated extension cab(as use of extension jack diasbles internal speaker). One other thing that I have noticed, is that, yes, some of the tones using the 3 amp modeling 3 position switches, are a bit muddy at low volumes, but at stage levels they do cut through rather nicely.

Support:
No clue! The need has never arisen.

Overall:
Other than for minor subjective flaws, as listed above, the unit hits a home run for overall ease of use, portablility, quality, and visual asthetics.

Feature:
This has almost everything you can think of in an amp. Tuner, even comes with 2 button pedal, 2 channels, and memory for each, 99 FX settings and all the usual FX like reverb, chorus, delay, flange, compression, and several more. I don't like the switch being on the back of the amp, but that's a minor gripe. 3 band EQ, master volume, tons of inputs and outputs in the back for direct recording and loops, more then any amp you will every buy.

Quality:
Well, it's an open back cab and the build feels fine and sturdy. I can't say much since i haven't had it long enough to confirm longevity of the internal components so to be on the nice side, i give it a 7 for now.

Value:
It has the most features you'll get for the money in a 30 watt amp. It's not 10 because value is relative to the usefullness of the amp's quality of the tone and not just features for the money.

Desirability:
It all depends on what you want to use it for so im giving it a neutral 5. I'll explain more below. If i had to do it again, i wouldn't buy this unit again because the tone just doesn't cut it for me.

Sound:
Sound is muddier and more softer sounding then a regular non-modeling amp. It is far from sounding like a good tube amp and in some ways better then a solid state, but lacks the cutting edge of a good clear tone. It's like the tone controls from radios back in the days when you had one knob to control bass/treble. It also lacks harmonics because it's lost by the modeling amp's blanket. If you want soft tone or compressed acoustic tone, this does a great job of it. If you want rock and metal with edgeness, you will be very dissappointed. There is a almost enough distortion for metal but it just doesn't cut through. If you play with the different settings, you can almost get a breaking, slightly overdrive tone but not a good one. Now the FX portion is good for some but not good for most. The best FXs are reverb and compression. Chorus is ok. Flange is ok but weak and rest are weak and some that are really just gimmiky. There is a 3 position preamp slider switch, 3 position gain preset like switch, and 3 position cabinet selector switch (aka more like a bad eq presets). The 3 eq knob's effectiveness varey alot depending on the 3 switches.

Support:
Don't know cuz i never called them for support yet.

Overall:
I give this amp a 7 because it really only has like few useable tones. Rest are either too muddy or thin and sound like a broken car speaker. The FX are ok. If you intend to use this amp for just practice and u want something to play with and tweak cuz u just like to do that, then this amp is for you. If tone is your number one priority, this is definitely not the amp for you. Listen to the 15 watt Vox Valvetronix for almost the same price. It's only 15 watt but if you hear it, you'll know the clear difference in tone quality of what an amp should sound like. I think this amp is fine for practicing and beginners and probably still sounds better then some solid state cheap amps in this price range.
