HD15 Combo : Nice tiny amp

I'm kind of experienced with electric guitars but this is my first bass amp. Bought this for bedroom practice, it obviously isn't loud enough for any rehearsals or gigs.

Build quality is good, didn't notice any blemishes, everything is working correctly. This thing delivers much more low end than I expected from low-budget 6.5 inch speaker combo. Tones that I get from it totally satisfy me as well as how the volume knob is working (HD15 isn't overwhelmingly loud for a bedroom, yet still it can produce some pressure as well as make really quiet sounds suitable even for practicing through speaker at night).

I would consider it perfect for me if there were FX loop and overdrive section but I think that's too much to ask for the price. Otherwise the amp is really good in my opinion.
