Personally I prefer JCM800 (KK because it's cheaper as you said) because it's more simple (1 chanel) and because JCM800 sound is br00tal. But mostly because the less knobs the better for me. I mean I've never used the clean chanel nor the Gain 2 in my Randall. The only things I change sometimes are mids/bass/trebble/gain. But pleasy move it to the GP thread because as you said is really off-topic (or add a guitar to the basket and then we'll talk about both which won't be so off-topic.
