HB-20R : Simple amp

For someone starting out,

I wanted a modest amp when it comes to price and knobs.

The amp is pretty good.

I think the reverb could do with some improvement.

Overdrive channel is nice.

I couldnt figure out how to control the volume of backing track if I plug one in. (but it could be my fault).

I haven't tried line out.

My idea before buying this was to have a good amp for a beginner, to be able to play around in my room/house.

And it has served me well for that.

One thing I did notice was that amp would switch off sometimes in the middle (which I assume is power savings?)

And putting the jack in contact with a metal surface of the guitar connector to turns it back on.

Often times this happens in middle of when you are playing. Which can be annoying.
