I've never played through one of these amps you've got yourself, but as matey boy said, it makes sound so it's a start. I had a carlsbro cobra lead off my older brother for years, and although it made an awful noise most of the time, a bit of love and attention and I began to believe it was alright. And, being fair, the amp wasn't the make-or-break of 'my sound' then anyway. It was more of a problem getting my fingers to move to the right places at the right time. Come to think of it, that's still the bit I struggle with...
What I mean is, after 5 months playing you have more important things to concentrate on, such as being in tune and learning the difference between a dominant 7th and a major 7th. That's nice and patronizing isn't it 😛
