HB-20R : Review from total beginner: So far so good

Just to be clear - I am a total novice and I with that device I am setting my first steps with playing electric guitar.

I ordered that amp as part of a bundle ("Fender SQ Affinity Tele MN BB Bundle1"). The amp itself makes a good impression (seems solid / well built). After 1,5 months of usage the device seems to work correctly. I cannot say much about the quality of sound from the speaker, as for the sake of my partner and neighbours I solely use the headphones output.

Advice for total beginners (and maybe manaul writer), as I am/was: During first attempt to use the amp I had no idea how to activate it. Like: once you plug it in to the socket and turn on, the LED light turns green. I have IT background, hence that was an indication for me that all is good/done, however the amp did not play anything (even after plugging in guitar), so I thought that it was broken. Only after review of few youtube videos I noted that amp' LED of ppl playing it is red, not green. Then I noted that you just have to be less gentel with pulling guitar strings to activate the amp.

With all that written, I guess this is a nice device to start with - especially that it comes as a bundle, which make it easier/more secure for total beginner.
