Just about if not everything Behringer/Bugera have their name on is a cheaply made clone of something else. The 6262 is a shameless 5150II/6505+ clone. But for what it’s worth the 5150/6505 series is essentially a tweaked Soldano SLO 100 circuit mass produced in more affordable fashion.
The handful of Bugera’s I’ve played/heard honeslty weren’t bad. I mean, even if you clone a good amp with cheaper parts and cheaper build methods, that doesn’t mean it’s going to sound bad. If you like the tone of the 5150II, the Bugera 6262 will probably sound good to your ears.
The real problem you’ll run into is the amp breaking. Which sounds like it happens to a lot of them when players take them outside of their bedrooms. Even well made tube amps are fragile things. Paper thin PCBs loaded with cheap components from low quality factories in China just screams “I’ll break if you move me” to my ears.
So the recipe is cheap and mostly good sounding amps that may not be the most reliable things ever.
In my opinion. I wouldn’t do it. I love the 5150 series and have owned several over the course of time and been in bands with a couple dudes who have had them as well. They are cheap enough if you buy them used and in my experience they hold up well with the road.
