I use this as a practice amp, when I'm either warming up/working on licks or practice regiments, or if I'm trying to write riffs for songs. With 27 possible combinations for its selection of analog modelling settings (which allows you to select between three classic amp, mode, and speaker settings each), it actually has a lot of versatility and fairly decent distortion tones if you're willing to dial them in. Funny enough, for a guitar it's higher gain settings leave a little to be desired (read: I've played through better. Played through worse, but I've played through better), however when you run a bass through it with high gain you end up with a very clear and punchy distorted bass tone (something akin to the distortion bass guitar you'd hear on a Nine Inch Nails record).
It has a three band EQ which does it's job, a master volume knob which also does its job, a gain knob which does its job, and one channel which as I said above can be used for either a clean or distortion tone (no means to select between them, so be ready to roll back the guitar's volume knob if you need to clean up - which, as a note, it does better than my Randall head does). It has a headphone output which I've never used, as well as a CD/Audio in for practice which, again, I have never used. For what it is, it's a pretty decent amp, and can actually get fairly loud (not as loud as a half stack of course, but for a 15 watt amp w/ a 10 inch speaker, it can crank); it might not be able to compete with a drum kit, and bringing it on stage might not be the best idea, but you'll be able to hear yourself if you're playing along to a stereo loud enough to piss off your neighbors' neighbors.
The biggest drawback for me is that pedals and external effects work like s#!t with it - if I try to distort it externally, it ends up sounding like a muddy, weak mess with no clarity regardless what pedal or tone i use or how much signal I'm putting in. Same goes for time, pitch, and filter effects - it seems to lose clarity if you send in anything but the dry signal, which means that if I'm practicing an effect heavy song or writing what might be an effect-heavy riff, then I need to leave the effects up to my imagination. (Not even a wah sounds good through it, and I've tried three different kinds).
Given the fact that this is the amp you generally get only with beginner guitar kits (y'know, the ones that come with the knock off strat or les paul, the behringer vtone amp, the strap and case that'll both break after 2 months of use, the thin cable with the plastic ends that'll sit in a draw for years once you upgrade, the tuner that doesn't know an A from an F, and one of a million DVDs where young guitarists can pick up all the basics for guitar that almost nobody ends up watching), it REALLY is of surprisingly good quality (especially since the one I have is second hand).
Solid 3/5: Pros: Good sound; nice selection of tones; GREAT for bass; good for practicing at relatively any volume. Cons: Sounds poor with any effects; No means to switch between gain stages
I bought this amp as a beginner and it was inexpensive, so it has fulfilled its purpose. Now as a more advanced player, I realise it is not that good. I use it on clean now with effect pedals, but would like to get a better one. Cheap price, not great quality. Would not replace this amp if I lost it.
For a 15 watt amp it has the sound of a much bigger amp. I love the various different amp settings that you can get out of it. This amp has as good a sound as a tube amp I had in the 60's. I would recommend it as a very good home practice amp.
See title. I needed a really small cab for my Micro Terror so I completely emptied the amplifier bits (they were equal to fecal matter anyway) and made a 1x8 cab out of it. It worked and I am happy with the result. With the Name Of Shame (Behringer) removed, it looks pretty decent. I also masked the controls etc. I even fitted an Orange decal on the control slab so it just looks like a black orange cab.
