I heard a country player using a MKIV last night and his tones, clean and dirty, were immaculate. I was amazed that it was a Boogie MKIV. He was running it in Class A mode. Are there any other Boogies that will get those fendery cleans? I would have bought that amp last night on the spot if he would have sold it to me. I owned a MKIII almost twenty years ago. It had the class A switch but I never ran it that way. Can anyone help? I'm need another backup amp. But I'm limited to about $1000 dollars. I might try to pick something up either in this forum or on Ebay. I do love the boogie overdrive. Thanks!
