Don't Let The Size Fool You. This Is The Real Thin

This amp is deceptive - it is a real powerhouse in a small package. Quite honestly, I was blown away the first time I heard it. Solid construction. Excellent tone. Fully customizable with 4 EQ controls. So, you can fine-tune it for any type of music. It has 2 inputs but only a single channel. Also has two 1/8" inputs. One for headphones (which automatically silences the speaker if they are plugged in) as well as an input for an iPod or other device so you can play along with a song or practice CD, etc. Works great. Perfect for practices or small jams. I looked at several options and am very satisfied with my choice. At this price and for this high quality it can't be beat.

Great small bass amp

Great value for money in this little light weight practice/travel amp. Plenty of power for a jam session/coffee shop gig as long as your drummer has a bit of restraint (remind him his ears will thank him later). It'll growl but not shake the walls, I have to roll off the lows and lowmids to get a clean tone with the volume cranked but it can be done. The EQ will coax a good variety of tones out of my JBass. Only complaint here is that I'd rather have a 1/4" line out than the second input.

Great for Guitar too!

I used this little amp when it was offered up by a rehearsal studio. I have been playing guitar professionally for years. I am a regular in the casinos in Las Vegas. I must say that this little amp sounded awesome with my pedal rig plugged into the front side. The 4 band eq was easy to dial in a great tone. Seriously. Guitar-sansamp gt2-delay into this little bass amp. It sounded great and was loud enough to be easily heard over our drummer. I am very impressed.

So IN my early bass days I played a gig in front of 400 or so people. I had the volume on this amp on 7 and it still shook the floor while providing some great tone. Definitely worth it.

Seriously, this little amp kicks butt for such a little practice amp. I can get a huge range of tones out of it with my Music Man Sterling. It also puts out an enormous amount of volume. Anyone who laughs at your little "Richie-Valens-in-the-garage" amp will shut up when they hear what you can produce with this amp. For practice and just messing around for fun, this is all I need.
