Multi-Watt speaker / ohms setup in 50w mode

Hey guys, I couldn't find an answer to this question in the literature so I asked Mesa, figured I would share.

In my old Mark hundred watters, its known that if I flip the switch to 60w mode to maintain a proper load match I would want to move the 8 ohm speaker load to the 4 ohm jack. I could not find anything about this in the Multi-Watt literature so I asked if this was also the case here or if the amp somehow handles it internally. I was told that the amp has no way to handle it internally so I can move the jack if I want to. Reading between the lines, I think that they're not worried about it since the OTs on Boogies are so robust, but I figure if I can have a correct match I'd like to since an incorrect match will change the response & feel.

Before I asked, one night I was rehearsing (loud) with my band with the amp in 50W mode in the 8 ohm jack and I noticed that I ran out of headroom- I had to dime the solo boost to get it to be a little louder for leads. I'll have to try it again now with the proper load..

I'd say email mesa boogie customer service. They are usually very good about getting back to customer inquiries.
