They just wanted to know why I sold 2 of them? The combo was way buzzier than the head. The head didn't start out that way. As a matter of fact - it sounded fantastic! After a few days of playing, it started in with the buzzing? Could be caps - could be the output transformer - maybe both? I'd expect that out of a late model Marshall - but not a MESA. I talked to a very well known builder who said that MESA has been using cheaper output transformers to cut costs? I don't know about all of that... How would anyone know that but MESA? I just know that I'm not spending $2,099.00 on an amp that has issues. I did purchase them off ebay - so anything is possible. I was going to purchase a combo directly from MESA, but have decided to just wait for the revised MKV. I'm sending my Mark IIC+ to Mike B. for a refresh - so maybe I can talk with him about the MKV. I would much rather have a MKV with the extra sound options, than just a Mark IIC+. I do think the actual MK IIC+ has a "faster" sound to it... If that makes any sense? It has WAY more gain too! If I replace the V1 with a 5751 tube - only then does the gain more match the MKV's more subdued MK IIC+ setting. The MK IIC+ has a clean sound that rivals my Cornford MK50H II. The MKV clean sound IMO is simply incredible! IMO - the MKV is more of a new amp - not a "historic" reissue of other MK amps. That being said - it just needs to be fine-tuned. Once MESA gets the MKV dialed-in, I predict it will be one of the greatest amps MESA has ever built.
