I ordered this practice amp because i got fed up with pulling out my normal amp, connecting everything and after that be finally ready to play.
This is way more convenient. Plug it in your guitar, plug in your headphones and go.
The unit itself feels sturdy and has some nice weight to it. However, there's not really a proper way to hold it and pull it out of your guitar without having the idea you break it. So 5 stars for quality (4,5 actually, but that isn't an option).
In terms of handling, it fits good on both my Squier Strat and my Epiphone SG. Not in the way of any controls or whatever. The controls work well, although it would be nice if they were visible while playing. The biggest 'downside' for me is the powerswitch, it's quite difficult to use if you don't have long nails. Again, 4,5 stars.
The features are amazing for the price. Rechargeable battery, overdrive and tone, and an aux in. Can't beat that. 5 stars.
The soundquality is good for this price. The overdrive works well, produces a nice crunchy sound (dependent on the pickups you use of course).
The downside on sound is that your headphones matter. I first used cheaps earbuds from Sennheiser, but that was all hissing and crackling. However, using my Sennheiser HD599 gave a beautiful sound.
All in all highly recommended. Very good item for a cheap present for any guitarist.
