I would go for the Peavey because of the of switchable effects loop. It just sounds too cool.
Since it only for the house, Peavey would be the best choice. If you like the tone, and you will use it for gigs, then go for the Marshall because it weighs only 16 pounds. The Peavey weighs 44.6 lbs.
Ay, 16 kilos pala the Marshall. Well, that's only 35 pounds.
