I can see you getting a list as long as your guitar lead of people's favourite amps but for my £0.02 worth... ANY amp with 3-400 watts+ will do if you just want more power. Every amp comes with a volume control, so 300 - 1000w in a spare bedroom isn't too loud; it may be a waste of power but if you went out gigging you'd not need to worry about buying a bigger amp! GK 700/800/1001 etc are great amps but do you like the tone?
