I am intending to purchase a GK rb700 head to go along with my Avatar b2x12 neo in the next few weeks (man im buying so much lately) the only thing is i tend to gig alot in places that could be 30mins to 3 hours drive away so i reckon im gonna get a SKB case for it.. the only thing which i assume is a problem (im probably wrong) is the cooling fan is on the top of the unit?? will that prove to be a problem??
