In my 26 years of playing guitar I have never owned a Marshall. I've played thru many of them but never felt they suited my playing style much or got the tones that I look for. They sound too ordinary to me, ya know what I'm saying? They have a sound that i've already heard a million times and I just don't care to hear anymore.
Plus lots of really arrogant elitist types like to talk about how Marshall's are the greatest thing ever... that and their Les Pauls. I've been in bands where the other player has Marshall's, Les Pauls and Strats, and that's it, they won't use anything else.
