I'd read plenty of reviews before choosing this amp over many of it's cheaper competitors. Some amps had the same wattage but the sound and features were inferior. For me, the Marshall AS50D delivered on all fronts. The sound quality is very good, and the 50 watts of power are enough for any solo musician to perform in a small-medium sized venue. This amp has the capability to take a guitar and a mic which is how I have been using it. The reverb and chorus effects are superb, especially the reverb, beautiful tone on my Guild acoustic from it. I have yet to have any issues with the sound, build quality or features which is why I have given this amp 5 stars. If you're stuck between this amp, cheaper models such as the Kustom Sienna and more expensive models such as the Fender Acoustasonic series, I would recommend the Marshall for the best value for money and overall performance.
