Sound — 8
I am using a Yamaha erg 121 guitar (which sucks) with the MG10CD. But a still manage to get an alright sound out of it. You can get a range of sounds out of it, from a warm clean sound to a crunchy metal sound. This amp goes suprisingly loud if you turn it up all the way, but with this volume comes a hell of a lot of squeely ear piercing feedback. However, at a sensible volume (even playing it with my crapy Yamaha) you can get a damn nice sound out of this amp. Especially if you put the gain all the way up or use a distortion pedal.
Overall Impression — 9
I love this little amp, it's easily loud enough for practising and great for any stlye of music. it's reliable, durable, flexible (meaning it suits any style of playing, not flexible as in bendy) it sounds great and it's compact and portable. If you need a practise amp I would recommend this. If you're practising in a band I would recommend the louder 15W MG15CD. Obviously you couldn't use this for a Live performance as it's only 10W, but it's a perfect practise amp.
Reliability & Durability — 10
This is an extremely reliable and durable amp. I bought mine second hand off a friend so mines quite old now, but it is still in almost perfect condition (the only thing wrong is the channel selector switch is slightly wonky, but it still works fine). This amp will never let you down, will last for ages and will take a hell of a beating to get broken.

This 10W amp is a good little practise amp. It has two channels, clean and overdrive. For clean there is just a volume knob and for the distortion channel there is a volume knob and a gain knob, and there is a contour knob which works for both channels. There is an emulated headphones input socket so you can hear yourself playing through headphones (the amp stops making noise while your'e listening through the headphones) and also there is a 'CD in & emulated line out' socket, enabling you to listen to cd's or tapes through your amp, or plug in a recording machine and record directly what you play onto CD/tape.
