Bugera 6262 vs Peavey 5150 [DI Ola Englud]

so basiclly the 6260 is a replica of the 5150?? it even looks exactly like it.. is this legal at all?
 
I kinda wonder, since it arent the same amps. The 6260 is the rippoff (wich does sound decent) of the 5150/6505, but is there alot of difference in volume? I just recieved my 2nd-hand Peavey 6505, and i also own a Bugera 6260. The first thing i noticed is, when the 6505 post gain is on 1, i have a very decent but full sounding "bedroom volume". While when i put my 6260 on 1. It is way to loud to use it without pissing off the nieghbours, and sound like it needs to be crancked up.
