I think Randall put the G12T75 in their 1x12 combos too....sounded nasty....first Archon 50 video sounds ....erm, horrible...and I think that's through a closed back 4x12?
Reza do these clips sound like the one you tried ,I am playing devils advocate here because i hated all the early clips the PRS clips themselves reek ,but the amp is much more accurate to these clips in person
FWIW I think the 1960 and Marshall t 75 are horrid speakers ,they scoop mids and boost treble and bass .The archon has a lot of mids that you don't want scooped IMO and you don't need to push the lows.
I am just saying anyone who thinks they suck .in clips( like me) should check it out ,The guitars used and cab will make a huge difference .I much prefer the 5153 cab with G25 over any Maeshall
