I don't know if belgium represents whole europe but if I walk into a shop selling mesa here in belgium I always see a lot of rectifiers ans stiletto's
(by the way the stiletto's don't sell too well), but never any markseries, neither rackgear. Yesterday I was thinking, what if the shop here in my city would sell some markseries. That would be great for them I think. The older guys looking for some santana tones would be really happy with a mark I. And also for the modern rockpeople that now play on a fender or marshall would find a great alternative in a markseries.
The metalheads, now always getting suggestions to buy a rectifier, would see the mark IV and try it. I think more mark IV's would be sold than rectifiers, because a lot of metalguys don't know how thight and heavy that not agressive at all looking amp sounds. I remember when I bought my mark III while I was playing in my former band, the other guitarist thought I would better buy an ENGL or something. He never heard of a markseries and the first time he saw my amp, he thought the amp would be too softsounding.
A little while later, we were talking about his gear. He plays a XXX, and he was already talking about selling his peavey and buying a mark IV
I think shops are just so stupid to not put markseries in the shop and that is a big reason for markseries not selling too well.
Only a small percent of guitarists visits guitarfora, and the other ones follow the opinion the sellers in the guitar shop give
