I only chose this amp because I was desperate to have a small cheap practice amp for playing at home. To be honest I wouldn't really buy it again if it were lost. I'd probably look for a 40-watt amp or more. But if you're short on money and always practice quietly at home, then this is the amp for you

There are two input channels with one volume control each and a 4-band EQ. The amp isn't very powerful if you want some booming bass. There's too much unpleasant distortion. However, there's the "cd/line in" input. I once plugged in my cassette recorder and I was really, REALLY surprised how powerful the sound was, even with the volume control of the cassette recorder turned down. I couldn't believe that I was using a 15-watt amp. It sounded more like 80-watt boxes. If you also turn the bass knob on the EQ down, turn up the mid hi and treble knobs up, turn on all your pickups and tone on your axe you get a GREAT slapping sound. It really blew me away. Best thing is that I could turn the volume up without any problems.
I use a 4-string Yamaha RBX 170. I preferably play Rock and Metal, but the problem is that there's too much distortion if I turn up the volume/bass so I'm forced to play quietly (or without much bass on my EQ, which isn't any better). The good thing is that altering the EQ can obtain a very wide variety of sounds, from very deep bass (not too loud) to very bright slap-bass suitable sound.
This amp is absolutely foolproof. Dead easy to use.
I'm not sure about how reliable the amp is, I use it only for light practice, so it didn't go through any accidents or repairs yet. I dissected it once to see what's inside though. Tis still working.
