My practice amp is either my Darkglass Element with headphones or my GK 400RBIV 115 combo. Personally, with as light as they are, I would not recommend anyone getting anything less than a Fender Rumble 500/200 or Ampeg RB-210/115. Those amps are so light they can easily live at home in the living room, yet can handle a small/medium gig. Maybe in a pinch a 112 combo if you never plan to use it for gigs, but I would never go smaller than that even for exclusively home use.
