I have 2 amps a Blackstar HT5R and a Vox VT20. The Vox is fine for a flat and sounds great. It has a headphone socket and Aux in. The Blackstar was demoed at the same time as a Fender Bassbreaker 007, 5 and 7 watts respectively. They are both too loud for a flat. I use the Blackstar in a house and don't have it above 11 o'clock. The Vox I keep for the flat. Buy the AmPro. You will have it forever.
