im getting one of these heads soon. im leaning more towards the 6505 due to it having more lower mids making it thicker, "meatier". ive read up as much as i can about the two and often come across someone saying that the 6505 is too "woofy/boomy" in the low end. is .... gonna get all muddy in the low end? i really think i want the 6505 but cant stop thinking about this. factor in that i play an 8 string (rg8 w/BKpainkiller pu) and you can see why my decision is going back and forth like a vibrating 8th string. if i can i will obviously bring my guitar and try both but there is a good chance that may not be an option. any educated opinions on this? thanks in advance.
