OK I'm going to purchase a GK 400RB-lll within the next few weeks and I'm curious what cabs go best with this amp? I've tried the 410RBH but I don't wanna spend 900 bucks for a 4x10 and I don't even think the cab is worth that much money. I really want a 4x10 cab and at the most I wanna spend around $500-$600 or less if at all possible. I've always heard Hartke cabs were great with GK heads. I play a 410XL with an HA3500 at Mars and I really liked it however I prefer the GK400RB over it much more. Any suggestions? Experiences? Thanks.
