Okay, so a rig I'm thinking of saving up for is: Gallien Krueger 1001Rb head (£631 - $1050) Fender Rumble 410 cab (£255 - $424) The Gallien Krueger 1001rb head is 700 watts. Apparently, the Fender Rumble 410 is 1000 watts at 4 ohms? An (cheaper) alternative rig I was thinking of: Hartke LH500 head (£350 - $582) Peavey 115TVX... 800w at 8 Ohm... (£195 - $325) I play for a metalcore band, so I was trying to go more for a 115 cab for that great low-end sound. Sorry, I'm new to cabs I still don't get 4ohm and 8ohm that much. I presume you can't plug a head into an 8ohm cab? You need another cab to do so? Thanks.
