OK, At guitar center with some time on my hands recently and I decided to try every cab/ head combo I had the desire too.. So the unplugging and plugging and moving etc.. began. I've always owned only 410 or 210 cabs.. thinking that 15s are waaayy too old school and undefined, etc... I'll say that i tried Mesa cabs and the walkabout, GK heads/cabs, Markbass Heads/cabs, Orange Heads/Cabs... and mixed and matched them all.. To my utter shock and surprise as I was pairing down the heads and cabs i got down to a combination that KILLED!!!! I mean really really shined.. like nothing i'm used to hearing in guitar center: The GK MB200 head paired with the Markbass New York 151rj 1x15 cab. Holy Smokes: Gut Punch, warm mids, Studio level definition, glassy highs... absolutely beautiful warm rich yet defined bass tone. The kind of tone that is so good you don't care if you every leave your house because it sounds so good in your basement! I was so shocked at this combo i kept going back to different 410 cabs with that head and it just wasn't as good. That 1 fifteen speaker and the horn combo on that particular cab are to DIE for. I'm building a new rig: 2 of these spectacular markbass cabs and an mb800 GK Head!!
