Yes, I had a blackout/mm-04 combi when Blooddrunk was released but wasn't really satisfied with this tone. Here's a little pickup/gainboost history of mine: first I had a HZ-H4/PA-2 combo, then blackout/PA-2, then blackout/mm-04, then J-50BC/mm-04, then J-50BC/JE-1000, then HZ-H4/Je-1000. The last combo ist the best I ever had because the HZ-H4 has more gain, more bass, is more agressive and has a cleaner tone then the J-50BC. I think this is my final combo. At least for this guitar.
