Great sounding but hella weighty

I bought this combo at a local used instruments shop in Budapest in a hurry some days before one of my band's shows, so that I wouldn't have to haul my HUGE 4x12 cab and also huge amp around. Well, it is smaller than those, by quite a lot, but boy, is this combo still heavy. Sounds heavy too, I can't help but love this thing. Has great low end thanks to that 15" speaker, love the separate gain controll (or rather really hate how it's becoming less of a thing on contemporary bass amps), the eq is pretty sweet too, each controll has a nice range, and you don't have to max it out to make the amp sound like something. Despite being labeled 45 watts, it's very loud, managed to gig and rehearse with it without issues with volume, and we're a pretty loud noise rock trio, so yeah. Nice little amp. Also built like a tank, and easy to maintain. Since it's from the mid to late '70s I recapped mine, which was surprisingly easy in every aspect. If you don't mind the weight or are not planning to move this thing a lot, It's great fun I highly recommend it.
