Yeti owner here.  I absolutely LOVE my Yeti!  I played Marshall amps exclusively for 25 years because I thought that Marshall circuits had to come from the Marshall entity.  Thankfully I came to my senses and realized that it was their circuits that I loved, not the entity itself (especially these days).

My Yeti is the absolute best Marshall-circuit amp I've ever had, and I've owned just about all of the Marshalls ever made.
