Deep and light
The best part of owning this amp? Asking my mates to pick it up and watching their reactions. They can't believe how light it is. I dragged a heavy head and a twin 15-inch speaker cabinet around in my younger days, and it gives me infinite pleasure today to know that my bass amp is easier to carry than my toolbox.
At 40 watts, this amp puts out a strong signal. The bright, contour and vintage buttons increase the range. For my needs (jamming with friends and playing the occasional party), this amp delivers great sound at a reasonable price. And it doesn't break my back popping back into the Subaru when the gig is over.

Excellent low watt bass amp 4/5
Great low watt bass amp in todays market. There are many low watt bass amps in production these days, however this one in particular pretty much wins overall. These not only sound better than pretty much any another other small watt bass amp being made today, they are also much more convenient and all-around have better value and accessibility. They sound excellent, have versatile features and weigh virtually nothing; SUPER LIGHTWEIGHT! If you're looking for a great sounding bass combo amp that is also super easy to take on-the-go, look no further!

Just picked this up.
This came highly recommended by a bass playing friend of mine. Considering that I have always used an Acoustic 150b in the past, I wasn't really aware of the cool new lightweight gear like this. Sounds great, perfect for solo practice and small space jamming...and is perfect to use without disturbing others with headphones. Pretty decent price point too.

Sounds like it should be way heavier
Bass players everywhere: go to your nearest Fender dealer and pick one up. I don't mean buy it, I mean lift it off the ground. It's light weight is juxtaposed with a giant sound and great overdrive channel. Playing a bigger gig? Use the line out to play any sized-stage.
