I like the Glock head a lot. Very nice stuff, just not quite the power I like. But their heads are over the top quality and sound AMAZING! Cabs I haven't care for as much, but still awesome quality.
Cabs are like basses, not everyone likes the same tone or color of cabs. Thats why its great to have a selection of different companies.
You can't go wrong with the Glock Heads no Doubt, unless you just need more power then they offer. even then use a power amp and the Glock Pre section which is very clear!
