Cool. Thanks for the info. I like the idea of being able to send it back to Mesa for maintenance. It something I will definitely look into down the road, I am enjoying the amp too much right now to let her go. This is my first really Boogie, however I do have a SOB 60 watt head that I found...
Got my first Mark amp yesterday. It's a Mark IIc+. Serial number in the low 14xxx. 60 watt, no reverb and no eq. But I now get what the hype is about. Paid 1150 for it.
