Got a Metro Amps kit-assembled 12000 and it's my second Marshall, aside from my Bluesbreaker. The BB doesn't start breaking up until noon (at least) but the SL breaks up at volume 1! That's right. 1 on the Volume dial. The channels aren't jumpered and there is no OD pedal at work. Just a Joe Bonamassa Epiphone LP plugged into the top-left channel. It has a MV so it's quite loud when leaving the MV at 100% while on volume 1, but it strikes me as strange since the much lower-rated (wattage-wise) BB breaks up a lot later. Also, it has a ridiculous amount of gain. Is this normal?
