I'm sure this thread has been done to death but for those who have tried different combinations in their 4x12's let me know what you did, why, and what were the results. I had recently purchased a Marshall 1960AC wich is the one with the reissue Greenbacks in it but looks like a JCM 800. I found myself wanting to tame the Highs a little bit and decided to Change the Top two Greenbacks to Vintage 30's. So far so good kinda of peeled the Cranked Highs back a little but I cant tell much of a difference in the Clean Tone. I've seen some folks say put em in an X pattern but to me I want ted to tame what is pointed at my ears and felt the lower speakers should stay. What say you?
